I am currently upgrading from 2002 to 2005. I am using a custom menu that I am menuloading on top of the standard acad menu. My custom menu resides on a network drive that my users have read only access to so that they can't modify those custom toolbars. When I load this menu, my users machines are trying to write to the directory that my custom menu resides. When we gave them write access to the drive 2005 actually created the directory string (O:\Documents and Settings\stevea\Application Data\Autodesk\AutoCAD 2005\R16.1\enu). It seems odd that 2005 is trying to create such a directory structure since it should have no reason to do this. I am completely lost in what is going on. It would appear that this happening is one of the root causes to my users machines crashing nearly everytime they close a group of drawings. One other note, I currently have a users machine that doesn't crash when closing, but he doesn't have the express tools installed and has never had 2005's SP1 installed. Has anyone had any experience with these causeing problems?
