[Andy Fan]

After being a long time fan of this site and using it for numerous tutorials and solving problems I finally created an account to address this issue as well.

I have a project file with dozens of sequences open and I noticed that it often freezes as well when I switch focus between another program and Premiere. This is a very annoying problem, especially when I only switch away for a few seconds to do something else and switch back to find that Premiere is once again, frozen. If I click anywhere (I’m on Windows 7) the entire screen goes white to indicated that the program is hanging. After around ten seconds it comes back and starts working.

I’m running an i7 processor with 4 gigs of ram. I don’t understand why it would lag like this even if I haven’t even done anything to my project file. Switching between windows should not require Premiere to load any files or read/write to my drives.
