Now this is weird. I've been using my A2000 for about 3 - 4 weeks now, and have never seen this. Today, for the first time, I got a weird boot up screen that says 'Optimized For Best Workbench Performance' then in the lower left hand corner 'Dolby Stereo', and in the lower right, 'THX'. What the HECK'S going on?? The screen is dark blue, gray, and black.
