Yes, I know about this Tony, and it's a much milder problem that the "large fonts" problem. I think it has something to do with the "<UNREGISTERED>" notice in the menu bar flowing over the row when the font is too large, and then it starts to flicker because a resize event is issue everytime this happens, putting it into an endless loop.

Anyway, if you register, you will get rid of that menu bar notice completely, and you might just be able to run the program in the normal mode without any problems at all! *hint* *hint* ;-)
