If you try to continue in this situation, you won't be able to even click the buttons because they are not in the right place.

Actually, I think I found part of the problem. It is the magnification system of Windows 7, turned on by default to 125%. It seems to be feeding false signals to the SAM Simulator program.

So, finally the thing starts in 1920x1080 and I can actually click the buttons. Unfortunately, for some reason the sound doesn't come on, and also, the display is choppier and slower than on my 4-5 year old antique (Core Duo 2) laptop computer. I'm using an i7 processor, by the way.
