Thanks for the reply. I am not sure I made myself clear, but  it seems
like this is a different way of approaching the problem.
I just want to be able to have a wire-frame box like so many apps do
when selecting an area to "select" or "zoom".

I was actually looking for a vcl friendly way to do this, or perhaps
find out if there was reasons the way I had mentioned were not
advisable.

Thanks again,
