2007 Crashes with multiple drawings open

[clarkrj]

We have been slowly migrating to AutoCAD 2007 with CADWorx 2007 for a while now. At first, I had very few problems with 2007, and those seemed to be only on one machine. Now I am finding the problem with all of my machines. From a previous thread I read a problem with drawings from an older version of AutoCAD (all the way back to 2006) locking up. Has anyone had success bringing drawings into 2007 without the lockup problems?

I think there are many reasons why AutoCad 2007 crashes.

I have all of my files saved in 2000LT format using the options settings.
I haven't had any file type issues.
