WM_SETREDRAW is used in two places in mdi.c, both of which don't do an InvalidateRect/UpdateWindow call after the WM_SETREDRAW guard. However, these don't have an effect. It might be a redraw bug deeper into the windowing logic that mdi.c is making use of. > Before > fixing the problem we need to understand what exactly is the sequence > of events that leads to it, how Windows and Wine behaviours differ. I understand this. - Reece
