Paul,
You should be able to see the node switch to reverse video (dark BG
color, light FG color) even if the node uses the same icon for Open and
Closed.
When I try it, the only time the node doesn't switch to reverse video is
when it has children and it is already expanded. If it has children and
is not expanded, it expands and switches to reverse video (or remains in
reverse video if already in that mode). If the node doesn't have
children, it switches to reverse video (or remains in reverse video if
already in that mode).

Randy,
I think I understand what was happening. Your code does work. However,
it did not produce the results I was expecting exactly. When a node is
"selected" it is not necessarily shown with "dark background white text"
while everything else is shown in "white background black text" which is
what I originally had in mind. Instead, the iconOpen icon is displayed
while every other node displays the iconClosed icon. The problem I had
was that iconOpen and iconClosed were set to the same icon, so I could
not see any results from running the new method. Once I changed the
iconOpen to something different, it works, i.e. a different icon is
displayed when the method is run! That is not exactly what I had in
mind (wanted "dark background white text") but it will serve the purpose
in my application, which is showing the user where along the tree they
are when navigating through the multiple screens.
Thank you yet again Randy (& Richard) for your help with AF! I'll let
you know if the SAS tech support track I opened for this issue yields
any additional tricks.
