desktop rez changes/can't access taskbar after playing game w/Wine

[Monkeyman]

I got things to work but I want to know why.  If I uncheck the "full screen" box in the game before I close it, my desktop stays normal.  This is an easy solution (I'll mark the topic "solved" in a minute) but I'd really like to know why it does that.  Is it just an oddity with Wine?  Is there some sort of command I can use to keep this from happening again without the workaround?  I have other games I plan to load using Wine so, if there's a permanent solution, that would be nice to know.

Thanks to all who replied.
