Yes it is still a good idea. The SSTab changes tabs by moving all of the
controls on the previous tab out of view, i.e. Left = - 75000 and then
moving the controls for the current tab back into view.

I've never seen it but have heard that in certain situations, the SSTab gets itself
confused with moving its controls around. At any rate, the prevailing
wisdom is to assign a frame or picture box to each tab and put you controls
in those containers.

Personally, I prefer the TabStrip control but that is a subject for another thread.
