I have seen the taskbar icon change to 2 icons during these times, one says 'Autodesk Inventor', the other says 'Ad Applicaion Button' then, when Inventor comes back to life, the button is dead.
I don't think it is a graphics issue as I have the latest drivers installed on a Quadro 2000 card.
Could this be a problem associated with having multiple displays?
I have also noticed that Inventor now 'steals focus' from other programs. If I am on my 2nd monitor with another program as my active window and I mouse over Inventor it steals the focus away as soon as the stupid 'part number eye-candy box' pops up. Is there any way of stopping this from occuring as it is really annoying when I am typing an email and Inventor pulls focus away from my typing. If I don't notice straight away I am running all sorts of commands in Inventor.
I don't recall previous versions of Inventor having this problem. Is it a bug which has added with the new popup eye-candy?
Sorry, I'm out of ideas. I've never experienced anything like this in any version of Inventor. The multiple displays angle sounds the most likely, but someone with more experience in that area will have to jump in here.
just wanted to let you know that you're not crazy. I experience the exact same problem. The only solution I have is to wait and eventually Inventor starts working again. It just does a really poor job of communicating with Windows. Windows thinks it is not responding but it's just thinking. I would appreciate if Autodesk made a progress bar or something so you can tell that the application is not frozen.
Yes, this is an issue that needs fixed. Usually a response window tries to open then goes to the background where it cant be accessed. This leaves you stuck and unable to respond to the querry you can't see. It does not always work, but if you double click where the I icon should be it will close the program and save a temporary rescue file. As I said, this does not always work, but beats redoing work if it does. Best of luck
This doesn't solve your problem of why and how to fix, but I can tell you that I save often enough that I am never concerned about retrieving any lost work. I can quickly recreate 5 minutes of work. Not that I save every 5 minutes, but that I don't not save anything that would take me more than 5 minutes to recreate. Not saying that I never crash.
If loosing work in the next second would be a significant hassle to recreate, I save.
I have never opened an oldversions file, except when helping others.
