Turbo Vision has a somewhat sharp learning curve, but once over the hurdle
its great.

1. You have used TListViewer on a TWindow, not on a TDialog.  This causes
the palette to be wrong.  Certain items in Turbo Vision, buttons, list boxes,
are designed to be inserted onto dialog boxes and not windows.  The palette
for a default TWindow is not large enough to handle these objects.  Compare
the palettes for TDialog and TWindow.  See the difference.

Flashing white on Red always means that you have a bad GetColor call
and that the palette indexes could not be followed up to the application.

2. Don't use TListViewer.  Its not made to be on a resized window.
   Use TSCROLLER.  This works like a champ and all that you have to write
   is the Draw procedure.  But you can find an example for all of this in
   the Turbo Vision book on around page 40 and upwards.  Read it.

Im also looking for other Turbo Vision crazies, besides myself.  What the
use of learning it all if I can't discuss it with someone.
