------- Additional Comments From thunderbird2k@gmx.net 2007-15-04 04:48 ------- The patch wasn't intended to work for all programs. It works for the majority of the programs. Though unfortunately this approach isn't acceptable by Alexandre as it does things which aren't very nice. These things can't be fixed.
The only real way according to Alexandre is to more or less revert the X11 window management rewrite by giving each child window an X11 window. This is the only way left and somehow this must be done but I doubt it will be done anytime soon as this patch would then affect ALL programs on wine from notepad to office, from winemine to halflife2.
