--- Comment #1 from Mel winehq@the-eend.org 2008-05-10 04:28:49 --- As an addendum, I don't have this problem with KDE 3.5.9 + Compiz, only when I use Gnome + Compiz. Ctrl is not used for moving windows with the mouse in the Gnome settings, nor does it occur with button1 in any Compiz config.
The problem is still present in 1.0-rc1
