I, too, am experiencing the "video mess" problem with 1.46f on my IBM ThinkPad 600. The problem does not occur on my desktop, nor does it occur on my other laptop, an IBM ThinkPad 560.

The only difference among the machines is that the ThinkPad 600, on which the video corruption occurs, is running Windows 98, while my other machines still have Windows 95 on them.

I would be interested in learning which OS is being used by the others who have reported this problem, and whether anyone has figured out a fix for it. I have tried to change screen size, have played with the shortcut properties, etc., but ultimately I have to quit and re-start the program to clear up the display problems, if only briefly.
