This is a plethora of issues that's just appeared on me and I really have no idea what the heck happened. First let me explain what I did right prior to this occurrence. I had a drawing that I was viewing paper space. I wanted to reorient the way it displayed model space using the mvsetup command. Anyways, I reoriented the drawing the way I wanted and later changed my mind. With a series of undo commands, I got it back to the original orientation.
Immediately thereafter, my CAD has been screwed in the sense of convenience. I've completely lost double click commands. I double click and nothing happens. It doesn't give an error or anything, it just doesn't acknowledge the double click.
I've also been forced to use buttons and direct keyboard commands. I can't just select something and hit delete to erase it. I have to either use the 'erase' command or button and then click on the object, then hit enter to confirm.
That brings me to the third issue. Any command I want to do has to be entered first. Then I have to select all the objects it'll apply to and then hit enter to confirm. This is a real pain as I'm very accustomed to simply selecting an object, typing 'm' for a move command, and having the program understand that I only want to move this one object.
I'm at a loss of what to do at this point and am considering an uninstall/reinstall. So far reloading old profiles and running a repair have not worked at all.
If the double click issues persist you may have to look into the CUI to see what the double click actions have musteriously reset themselves to. But the pickfirst variable is your likely culprit, and it has occasionally set itself to 0 on me without me doing anything.....
I hope my info was useful, but if by some odd chance it actually solved your issue, feel free to mark your post as "Accept as Solution". Thanks!
Your OP contained the answer to the problem. The end of your scenario says "With a series of undo commands..." and that is the problem. I noticed this in version 2007 and have seen it exist in subsequent versions through v2010.
There is an option IN the mvsetup command to Undo the results WHILE YOU'RE IN the mvsetup command and you should use this. If you use the command line version of the undo command in any of its forms (ctrl+z, toolbar or ribbon buttons, QAT...) to reverse the results of mvsetup AFTER IT IS COMPLETED, AutoCAD sets the pickfirst variable to "0". (Go figure.)
Here's a freebie: If you have a custom VBA program and use the command line version of the undo command in any of its forms (ctrl+z, toolbar or ribbon buttons, QAT...) to reverse its results, AutoCAD sets the filedia variable to "0".
You are correct about the rotate feature of mvsetup. Do you know any shortcuts to accomplish the align feature across viewports without mvsetup? This is what we use it for and i just can't make the users understand "do not undo mvsetup" and i can sympathize with them because why should they understand that. They should be able to undo any AutoCAD command, shouldn't they?
