--- Comment #2 from Lei Zhang thestig@google.com 2007-10-29 12:37:37 --- Please add a conformance test [1] to dlls/comctl32/tests/propsheet.c to do something like the following:
1. create a propsheet with some buttons 2. resize it 3. look up the position of the buttons
then check to see if the behavior with your patch matches the behavior on Windows.
