Using the CVS WINE, Pokerstars works OK except the fonts end up looking a bit funky. Also, when leaving a table the Window Manager panics and sets the display to 1 pixel. Ultimate Bet won't install because the latest WINE breaks the Internet Explorer Installer.

At this point, I gave up on WINE. I'll probably invest in a copy of VMWare when I clear my next bonus.

Thanks a bunch to the guys who responded to this thread.
