I had this happen several years ago and can't remember what I did to fix it. When I start MM400 the screen is about 4 times larger than the monitor, I can scroll down to the bottom, but I can't get to the right hand side of the screen. Normally if I boot into PAL mode I can see the entire screen (if I stay in NTSC it looks like it does now). My demo copy of MM300 works fine (in PAL mode). I think it's some kind of PAL/NTSC problem.
