Ok I have an MK2a I'm running 2.00b11 with Hijack 220 other wise no other hacks. At first I thought it might be software refreshing the screen but it seams to be a random flicker. It will flicker at least once every new song but usually happens a few times a song. Is this a software or hardware issue? Oh it's in my home when I notice the flicker (don't think it's the dimmer thing but I'm most likely wrong.)
