I've had instability issues using APE on both a G4 powerbook and a dual G5 powermac going back to version 1, but i keep it around out of necessity for app's like Audio Hijack Pro. Using the Master Exclude List has not seemed to be effective for me. As it is now, I have to quit the 'aped' process whenever I need to ensure stability which has become an annoying, repetitive task.

I've had many different app's crash and I check my crash logs whenever there's a crash. 9 times out of 10, APE has been running. I'm not commenting to bash APE because I do enjoy what it allows me to do, but after 2 years of use, the instability outweighs the benefits. I do hope APE will achieve better stability. I'd use it all the time.

Check out WiseWeasel's post too. The fellow knows what he's talking about.

umm. ignore list not working on my powerbook or g5. tried toggling checkbox and switching apps and when that didn't work i tried relaunching app. "go idle on ignored app's" checkbox is checked, speed freak is on the list, ignored list is enabled, but S.F. still accelerates itself. what am i missing? other than that it does what it says, which gives a nice added pep to my app's.
