--- Comment #5 from Dennis Schridde lindevel@gmx.net 2007-08-17 19:00:35 --- I just confirmed (on WinXPSP2 in a VBox): On Windows XP OPEN_ALWAYS seems to work as well (opposing to the info I initially got from someone else on IRC).
The testcase currently uses testdir in the "current directory", which, according to MSDN, is not supported. It should instead specify an absolute path, eg. "C:\testdir". This doesn't change anything, neither on the Wine side (where it still does not work) nor on the Windows side (where it still works). (With OPEN_EXISTING and absolute paths, it also still works on both sides.)
