Simple fix

I'm pretty new to the code, so it was a bit of a struggle, but I seemed to be
able to fix this particular application by appending a line that seems to cause
the driver to exhale.

I added the line at the end of update_now(), so it pretty much only applies to
applications using the UpdateWindow() function. I got the idea from the
RedrawWindow() function, which calls the same driver function just before it
starts sending WM_PAINTS. (which seemed a bit odd to me, but I'm sure it's
there for a reason)

Thus I didn't see any difference in a few other applications that have painting
issues. But for this test application it does the trick.
