I also don't see the benefit of disabling a button on a page the user can no longer see unless they reactivate the page, at which point you re-enable the button anyway. If the button was on the form instead of the page, disabling/enabling becomes relevant.

Ahh. Are you *floating* the buttons over the page frame instead of dropping them on a specific page so they are visible to all the pages? Or dropping them on the form instead of the pageframe?

I think you would be better served by basing the Enabled property of your buttons on PageFrame1.ActivePage property [ IF ...ActivePage = 1 ]. You could place this in the refresh method of your buttons and call it from the Activate method of the pages [ThisForm.Button1.Refresh()].
