Hi Dave,
You will often get answers very quickly in the newsgroups. There are lots
of smart people who frequent here. However, for the most part it is peopled
by volunteers so there are no guarantees.
I'm not sure I understand this question. Are you saying the tree control
takes focus from the form simply by moving the mouse up? If that is
happening is there possible some code in your program that is setting the
focus to the tree again perhaps in a SetCursor() or MouseMove() call or
something like that? Perhaps posting more information would help to spark
other people's comments.
Tom
