Maple freezes my laptop when I go into windowed mode

Once I go into windowed mode, the section that MS would be taking up would go entirely black, as would any other windows I'd have open. I can't click on anything after that either, so I have to force a restart. I'm running WindowsBlinds on my laptop, I think that has something to do with it (even though I added Maple as an exception to the theme). If it helps, I'm running Vista as well.

Any ideas? MS works fine as long as I don't alt-tab or go into windowed mode (I always use windowed mode though).
