If I have a form with a PageFrame and a TextBox. In VFP 5.0 if I press Tab from the TextBox, the cursor move to Tab text part on the active page of the PageFrame. From there I can press the left and right arrows to move from one page tab to another. How do I prevent this?

It appears as though the Page object receives focus, but I do not see a GetFocus or LostFocus event for the Page object. In VFP3.0, this never happened.
