using this fixed version works much better.. without all the crashing... actually I've tested a ton and it never crashed at all!

I can open a buncha bug reports if you'd like... i think all the main issues are in the switching from rootless screen 0 to any of the other screens... or vise versa, and you already said it was disgusting, so you might be expecting all these problems.... so I thought I'd write out what I've seen here first.

Wine still has issues, and quartz-wm I believe.

Running a fullscreen only game (Neverwinter Nights) all went well, it launched and went into fullscreen and I went in the options it saw all the modes available and i could click through and use each one, very nice! (this game has no window option)

Running Neverball was a different story...

If its set to fullscreen at any resolution and I launch the game, it does come up fine, eventually even though its hung on a blue res change screen 5 to 8 seconds... (sometimes very fast, sometimes the blue screen and res changing happens multiple times before the game shows up... and takes over 10 seconds)... i can change a few screen resolutions around, and it seems to work, but occasionally, usually while going up to a higher res, or back to max screen res, i just see a quick white fullscreen window do the genie effect down to X11.app... the game music keeps playing, but the game is no longer accessible... although the music is still playing and the wine processes are still going along like nothings wrong.  Its not listed in X11 as a running app anymore on the top menu or right clicking the dock icon, though the xterm i started it from thinks its still going.  This same thing happens if I use CMD+H to hide the app... its gone... with the sound still playing, and I can't ever get back to it without killing wine (or ending the process I launched from the xterm) and starting over.  Going back and forth between rootless and fullscreen a few times does this as well...

When switching from fullscreen back to a window... quartz-wm doesn't kick in... so theres no top bar.... when starting in a window and switching to fullscreen, quartz-wm doesn't stop and there is a top bar... and there are all kinds of problems with things being drawn in the right place like this.  I'm not sure if this is a Wine issue though... but its not a problem on Linux I've ever noticed.

I'll find some more programs I can use to test with to confirm issues... finding ones that work right in Wine on Linux is my first choice, so the error isn't a Wine issue...

ohhh... also, I noticed when it changes to fullscreen, xterm windows shift off the bottom so the top bar of their windows are barely on the bottom of the screen and I have to drag them up... didn't know if this was intentional to get them out of the way, but they never come back up on their own.

anyways... I'm excited, this is awesome  :-)
