--- Comment #5 from Knightlain pastorrub@msn.com 2011-09-18 08:28:52 CDT --- if(!hKL && !lpszDescription) { lpszDescription = (WCHAR*)HeapAlloc(HeapCreate( 0, 0, 255 ),HEAP_ZERO_MEMORY,255); } Those are the lines that fixed it for me, but I don't know to make a patch and I know more implementation is needed for the function to be correct.
