No thats not standard, but sometimes required when the kernel
button interface is screwed up. This is probably fixed in a later
version of the ipaq kernel.

Win32 uses window procedures (winprocs) and messages
to make everything happen. The window background
is drawn by DefaultWindowProc after the WM_ERASEBKGND
message is sent to your window procedure and passed along.
If you catch that message and return 1, the background won't
be drawn. I think this method is used in some of the win32
sample code, src/demos/mwin/*.c
