------- Additional Comments From vitaliy@kievinfo.com 2007-09-02 17:47 ------- + if (!data->managed) { + /* Even if "Managed = Y" is found in the config file, fullscreen windows */ + /* are marked as unmanaged */ This is not correct. If Managed=N _all_ windows are unmanaged - see the top of the winex11.drv/windows.c Which means you should never disable "Managed".
So if you have this problem, then you purposely introduced that problem.
If some one have Gnome's task bars over their window see bug 4876.
