Program Crashes

We have 4 copies of LT2002, all running on Windows XP Pro on new Dell
computers. All computers are different models. All continue to crash and
there is a pattern that is starting to emerge. I am wondering if others are
seeing it.

Those with the most crashes are the fastest ones. It usually happens when a
menu or box is being pulled down, and icon is hit, a popup box is about to
appear, or change of focus from the drawing window to some other window like
properties. All of these generate Windows interrupts or commands from
Windows that are passed to the AutoCAD. It generally happens when these are
called up very quickly after some other command is executed. It seems like
when AutoCAD is not finished with one command and Windows issues another one
it crashes AutoCAD.

Usually there is a warning before the shutdown. Often recovery files are
generated but not always. On rare occasions Windows just closes AutoCAD
immediately.

This kind of bug would be very hard to find and deal with. Every piece of
code in the program works fine by itself. It is a matter of the timing
between two commands.

Again, is anyone else seeing this????

Yours truly, Michael Barb

Michael,

I've been a drafter for about 8 years (3 professionally) and I have continuously experiened the same probelms which you have described. Without sounding like i'm tooting my own horn I can honestly say I am pretty darn fast when working with AutoCAD. I use the keyboard exclusively and most of the time find myself going faster then the PC. I've worked in about 5 different offices and have worked on all versions of AutoCAD R10 - LT2002. I thought I was cursed because every new job, or every new PC would crash constantly with me on it regardless of OS or version of CAD. I do agree with the point you made about it happening to the faster drafters, because most of my colleagues never have trouble, even though were running on identical PC's. As far as fixing these problems - I have no idea! I just thought i'd share my experiences and see if this happens to others. Thanks,
Matthew Corbin

If you have ATI graphics cards in those machines, hop on ATI's website and
get updated drivers. Also explore turning down or off video card hardware
acceleration in Windows>Control panels>Display... . Also make sure you are
not running the video cards at maximum settings (no need for 32bit True
color and 1600x1200 maximum setting, refer to recommended settings by
manufacturer).

Also update your mouse drivers (MS Intellimouse work best, it does not
matter who's mouse you have), make sure your Windows is up to date with all
it's patches. Place LT in the Exclusions section.

All your add-ons (ZIP drives etc.) need to have updated drivers too. Your
anti-virus software needs to be turned off (or set to default factory
settings at best): remove any so called 'crash-proof' software if you got
it.

There are also patches for LT2002 that address graphics issues, see if that
helps too.

Some have ATI card and others do not. For the ATI cards we have turned off
the accelerators per Autodesk suggestions. We updated all the drivers and
dropped the colors down from 32 bit. We have updated the BIOS on the mother
board and vidio card.

We updated the mouse drivers and I put the MS Intellimouse driver on several
machines. I like it better also.

We do not use virus software on the seperate machines. The network people
have very good firewalls and server protection as well as strong rules about
using outside disks. Or network people feel that seperate protection is not
necessary if handled properly at the gateways and with constant monitoring
by the server.

We keep Windows XP pro up to date with automatic updates. I have loaded in
all the LT2002 patches as they became available because of the ongoing
problem.

In conclusion we have done every thing you suggested and more.

As mentioned before most crashes occur on a pull down box or menu. Some on
display of a dialog box. Very few on hitting an icon or change of focus.
None on executing new commands from the command line. One reason I suggest
the sorce as being the interaction between Windows and AutoCAD is that I
have done some C++ and Visual C++ programming and can see how this could
happen.

This is just a shot in the dark, but after reading all that you have done, the
hangup seems like its a program running in the background that is using all your
memory, we have had this happen occasionally with LT and a newer faster computer
with the
latest OS. We have turned off almost everything pre-loading at startup, windows
services, etc to allow AutoCAD LT full reign of memory available and that
usually fixes it. Either that or one of your programs does not play well with
others !

I received the following this weekend. I am not sure if I should repeat
this but considering it is an open forum private comments like the following
should not be made private. If someone has something like this to say they
should make it to the entire forum and let AutoDesk and others reply. The
author was listed as "NoSpam" and the return e-mail address was
NoSpam@NoSpam. This anonymous way of sending message makes it even more
suspect.


"Autocad has it origins in the beginning days of personal computers. At
that time the only way to get good performance was to do things in assembly
and access hardware directly. There has never been an absolute total
rewrite of Autocad to eliminate all these little pieces. Unlike operating
system calls and newly compiled code these chunks of old code are not always
reentrant and cause all kinds of problems when control is returned to them.
Autodesk feels that the enhanced performance of these things still out ways
the problems that they cause. To deal with this they have built a very good
auto recover system. If you want to use Autocad this is just something you
will have to learn to live with."

"Your inference of speed being the cause is wrong. These crashes can come
at any time for any number of reasons. Those that are faster are simply
using Autocad more. By executing more of this old code they simply have
more chances for it to crash."


I am not sure that I believe it. I would think that in all the years that
AutoCAD has been running under Windows that by now all the legacy code would
have been removed. I also do not think that AutoDesk would intentionally
leave bugs like this behind. I would like some other opions of this
questionable reply.
