Hi Ben.

>The moment I resize the pageframe's parent form OR switch to another page and back again, the new control resets to its original position (0,0) and dimensions.

Try setting the control's Visible property to .T. before setting Anchor to 15. Also, right after setting Visible (and before Anchor), call control.ZOrder(1) to ensure the tab order is set properly (in case you have other controls on the page).
