Quick tip: if you get this error when starting vmplayer from the command line on RHEL 5:
/usr/share/themes/Clearlooks/gtk-2.0/gtkrc:59: error: unexpected identifier `animation', expected character `}'
Just open the file /usr/share/themes/Clearlooks/gtk-2.0/gtkrc and comment out line 59, like so:
#animation = FALSE
This doesn’t seem to affect functionality, but if you’re one of those people who wants their logs to be clean, the fix is easy.
