Yes, you could do this. Check the TLB geometry to see what size
it is before it is realized, if it's too big, reorganize, etc.
It's a pain in the neck, and you inevitably end up throwing in
a "fudge factor" of 11, or 17, or 33, or whatever it happens to
be that day on that machine. It will have to be something else
on the machine of whoever you give the code to.
Better to have a quick peak at the screen size and if it
is below a certain threshold say, the heck with it, two
columns for you, big guy.

Yes. But that doesn't guarantee your user is going
to find your OK button. Users can be pretty dense. :-(
Cheers,
