I did not read your code, but the narrative above sounds similar to what
I had experienced.

During WM_PAINT, using WinBeginPaint/WinEndPaint, I would create my
client window w/ GPI functions.  Any time after that, when responding to
various messages ( Listbox LN_SELECT/ENTER, Button3DBLCLICK, etc ) I
would do more GPI work on the client window, by using the WinGetPS /
WinReleasePS combination.

The problem that I had was that the WinBeginPaint invalidates the client
window, I believe, and so it has to be completely rebuilt.  All that I
needed to do was to make modifications to the existing display.
