Remove vsti's from existing project -ACID Product Family

I have Acid 7.0e and I have a 17 track project. 3 midi and 14 audio tracks. The program is responding very slowly. i.e. cursor movement, scrolling, etc. When I was establishing my midi tracks, I auditioned about 12-13 vsti's on each of the 3 midi tracks. The project "remembers" each auditioned vsti and now I suspect that a lot of processing power is being used and/or wasted keeping those unused vsti's. Problem is, when I open the vsti pull down window, I cannot figure out how to delete or unload the unwanted ones. Anybody else ever have this problem. Sure would appreciate any suggestions?
