I have done all of the typical cleanup for VS IDE performance.
Regarding the comments in the other post: A new machine is not an option. Small views are the order of the day in the CAB world. The UI designer is a main feature of an IDE, why would I scrap its use? And, I am a C# guy, already.
Have you tried to make a module specific solution in the DF/CAB environment? I think there will be a lot of hurdles to cross on that one. I do my best to close all code/designer windows when I am done for the day. I have plenty of disk space and am fully defraged.
Btw, other, non-CAB solutions, open in seconds.
Thanks for the tips,
Bill
