------- Additional Comments From mike@codeweavers.com 2006-30-05 00:18 ------- Wine can only work on one display at a time, so if there's any other Wine processes running, the DISPLAY will be taken from them first.
The first process that is run should honour the DISPLAY variable.
Try "wineserver -k" to kill other wine processes.
