I know you have probably seen a post titled Cedega that has this issue in it as well, however I felt a more direct subject was in order.
I am running Slackware 11.0 and like WoW and C&C 3. I installed Cedega not too long ago, and had it working perfectly with WoW (40+ fps). Then I got the bright idea to take C&C 3 from my windows over to my linux just like I did my C&C. I tried running it but it just sat there with 100% CPU Usage and did nothing. I ran killall wineserver (Which I had to do some times with WoW when it wouldn't exit correctly).
Then I tried to start cedega back up and try playing WoW. It did the same thing (100% CPU usage with no result). I also had this problem with WoW at times after I ran the killall command, but usually a reboot fixed the problem.
Now after I rebooted and tried starting cedega I got the error:
F1 2007-06-01 17:01:21,470 CRITICAL Unable to load GTK2 Python bindings: No module named gtk
I did some looking and found out that all I really need is pygtk. I have pygtk installed. I tried updating it to 2.10 with no end result. It still gives me this error. Currently I went back to the original 2.8.6 which I had no problems with before, however cedega still gives me this error.
Any ideas where I should go now?
