To keep it from happening, I have to wait 2-3 seconds before clicking anywhere else on the screen. Occasionally getting cpu overload errors, as well.

Could still be a plugin - have you tried opening the session with all plugins disabled?

You could also try a Save Copy in, or create a new session and import session data.
