Im running windows 7 on vm and studio 5000 is version 27. I opened a clients file this morning to add expansion i/o and drives and as i was adding the drives the software got slower and slower. so i saved and closed and tried to reopen and now sometimes it opens but its slow and other times it wont even open and the cpu usage on task manager is like 100% everytime i try open that file. But i can however open another file from scratch alot faster. Does anyone have any idea on this?
