The windows API is somewhat slow in many respects. To overcome this, certain
tricks are used to optimize things. Sounds like Borlans does something similar
to what I do in a COMM program I wrote. Use ScrollWindow to scroll the window,
and let Windows put WM_PAINT messages in the queue to refresh the parts that
are exposed. Since the WM_PAINT's don't happen right away, you get a look
similar to what you describe.
