Lately I've been experiencing weird things happening on my screen, but only when I'm using ME. When I do audio only gigs I have no such problems. This is what's happening when running ME lately. 1) Sometimes about 2 hours into my set my BPM's will either lose a decimal point or will disappear totally. 2) Time remaining on track will display a black box over the numbers so I can't see. 3) Sometimes the wave forms will turn a weird color like the color you know when trouble is about to arise. 4) A big pink rectangle formed across the screen I have taken screen shots of what my computer looks like when this happens that I can show you somewhere if needed. I'm usually in panic mode each time this happens so I believe simply shutting down ME does not do the trick. Shutting down both ME and Serato DJ will solve the problem.... sometimes. Other times I get these glitches again about an hour later. I can usually buy myself a couple of mins before the program totally crashes to setup my iPod for a reboot of both. Any ideas as to why this is happening? This could be a potential culprit and I try not to do this very often, but things seem to go awry when I either do a simple search on my computer for a file or If I open up iTunes, the internet or download a file.
