I think this was discussed at some length some time ago, so excuse me if it's repeating. I've just started with GPO again after a hiatus and the GPO String sections (X-custom) will "pop" or "blip" while holding. Is there a cure for this? or do I need to reinstall? I'm using the Oct. 2004 update on a MDD 1.25DP Mac w/2 gigs of ram and Apple's Logic 6.4. Thanks.
