winfont.c winmultiwindowshape.c winmultiwindowwindow.c winpfbdd.c winshaddd.c winshadddnl.c winshadgdi.c Fix incorrect wrapping of functions. Ensure the pointers from pScreen point to the called function even if wrapped functions changed it Set the window properties to NULL to avoid referencing freed memory because of timing problems after deleting a window Do not wrap ChangeWindowAttributes.
