--- Comment #3 from Will Tipton wtipton@hmc.edu 2008-08-07 15:49:30 --- Thanks for your quick response. It appears that infoPtr->tools[nTool].lpszText == NULL in dlls/comctl32/tooltips.c:TOOLTIPS_GetTextW (line 1563), causing the call to strcpyW to fail. Of course I have no idea if this is indicative of a larger underlying problem, but tossing in a quick
if (infoPtr->tools[nTool].lpszText == NULL) return 0;
seems to make it work.
