If you read the manuals thoroughly, you'd find that the only case where
SMART_REFRESH fails to entirely fix your window's display is when the user
resizes the window smaller, then larger. The NEWSIZE events are intuition's
solution to this dilemma. Depending on your specific application I'd suggest
using the SUPER_BITMAP type of refresh. This mode allows the window to easily
display a portion of the actual bitmap it's displaying, without any damage
ocurring. Investigate it further, and I hope that helps.
