I hate to add to this chorus, but quite simple GE 4 is unbearably slow and jerky. I've tried numerous variations with cache settings for memory and disk and nothing cures the problem.

I haven't has a chance to fool around with GE for awhile, so this was the first chance I had to sit down and spend some quality time with the app since version 3. I was shocked at just how bad performance was.

I mentioned that nothing cures the problem, but there is one cure which is reverting back to version 3, which is just as fast and smooth as ever.

It really is a night and day difference between the two.
