------- Additional Comments From andi@rhlx01.fht-esslingen.de 2005-27-07 12:19 ------- Check for changes in dlls/comctl32/, especially listview.c. And, like I said, try checking for WM_LBUTTONDOWN *changes* in the diff between the working CVS and the non-working CVS. Or, IOW, do a CVS regression test as documented.
Good luck!
