I couldn't find any other threads on this, so I'll try here. To put it simple, I can't get GTK Radiant to run in Windows Vista. I would like to point out that I already know about the "solution" written on qeradiant.com:
taken from http://www.qeradiant.com/cgi-bin/trac.cgi
Special note for Vista-users:
You have to disable the desktop-styling in the properties of GtkRadiant.exe! In case of wrong menu-rendering you can switch to the "Raleigh" gtk-skin.
The gtk-theme can be changed in [install-folder]/etc/gtk-2.0/gtkrc.
I have tried their proposed solution, and my immediate response was "WTF?!?!?!?!?"
There's nothing like what they're talking about in Vista from what I can see. Has anyone else run into this? Are there any REAL solutions out there?
