A recent change to dlls/comctl32/listview.c implemented GetSubItemRect, but this causes Xnews to hang when selecting a newsgroup from the list. I don't think the change itself is at fault, but it may have uncovered a bug elsewhere. The app gets a message LVM_GETSUBITEMRECT (4152) with the following parameters: wParam: 1078422692 (0x40476ca4) lParam: 1078422612 (0x40476c54) wParam should be a small integer (an index into the listview items) and lParam is a pointer to a RECT: *(LPRECT)lParam: {left = 2, top = 1079544291, right = 28246089, bottom = 1079843718} or {left = 0x2, top = 0x405889e3, right = 0x1af0049, bottom = 0x405d1b86} lParam->left is reasonable, but lParam->top should be a small index. Note that wParam, lParam, and lParam->top are fairly close numerically. The function LISTVIEW_GetSubItemRect then tries to loop from 0 to that huge number, causing the hang. I put a sanity check inside that function to stop it from going past GETITEMCOUNT and that works, but I want to see if I can fix it the right way.
