------- Additional Comments From lionel.ulmer@free.fr 2003-04-06 16:20 ------- Could you try to run it in 'Synchronous' mode (look at your Wine configuration file).
This should, if it still works, open the debugger at the failing X11 call. This will help greatly pin-pointing the error cause and trying to track it down.
