Hi!
Try deleting the control, then reinsert it, but make sure that first you have displayed page 2 of your tab control in design view. When you click the new tab control button on your form toolbox and mouse over the detail area of page 2, the background should highlight indicating that you have selected that particular page for the destination for the control. [!]Do not click unless the tab control is highlighted.[/!]
Let me know if this doesn't do the trick.
