Since this patch: http://www.winehq.org/hypermail/wine-cvs/2005/06/0338.html SHGetPathFromIDList() seems broken. The problem is that files stored in the Desktop directory don't get the path to the Desktop directory prepended. I've tried to fix it in the attached patch and added a testcase, but the shell COM interfaces easily confuse me, so perhaps someone with a better understanding of this stuff should look it over before I submit it to wine-patches.
