You will see some of us haven't upgraded yet!
Anyway this is about that new beast (intro'd in 2006) called the customisation file.
The problem I'm having is that no matter how many times I modify the file, apply the changes, and save it, every time I open AutoCAD the previous version of the customisation keeps coming back. This would only be a severe irritation except for the fact that my old file contains references to custom menus i have since deleted. So of course every time I run AutoCAD it tries to load the menus, fails, and takes great pleasure in telling me it can't find the menu files.
If I watch carefully it seems there is a lisp routine that is being called by the customisation file, and this routine is trying to populate the menu and toolbox items.
I seem to be missing a trick here - can anyone help?
