--- Comment #2 from Kirill K. Smirnov lich@math.spbu.ru 2008-04-17 07:55:06 --- Should be fixed in current git thanks to patch: Vincent Povirk : tools: Modify wine.desktop to use start.exe /unix. http://www.winehq.org/pipermail/wine-cvs/2008-April/042588.html
(I do not know why my patch was rejected, but the problem is solved now).
