--- Comment #8 from Louis Lenders xerox_xerox2000@yahoo.co.uk 2008-03-12 17:25:19 --- I see a lot of fixme's in my console from SHAppBarMessage.
There's been a patch for this function a few days ago, so that could be the cause: me and Lei use current (where the patch is in) and you use wine-0.9.57 (whithout that patch) If possible, try use in current git,and otherwise see if wine-0.9.58 fixes the problem for you.
