--- Comment #8 from Philip Nilsson leffeman@gmail.com 2009-03-08 13:10:56 --- Running with +dialog the log ends at this line.
trace:dialog:DIALOG_GetControl32 L"msctls_trackbar32" L"Slider1" 1051, 190, 185, 65, 15, 50010018, 00000000, 00000000
I think msctls_trackbar32 is defined in comctl32.dll, which is not imported.
