Can't Click Anything
 

Frequently I will display a report in print-preview mode for users to either
close or print. But sometimes none of the buttons on the screen except the
Red X in the upper right-hand corner are available. I often turn things off
so before I display a print preview screen I do this:
Application.Cursor = xlDefault
Application.ScreenUpdating = True
Application.EnableEvents = True
ActiveWindow.SelectedSheets.PrintPreview
Application.ScreenUpdating = False
Application.Cursor = xlWait
Application.EnableEvents = False
Why would I sometimes not be able to do anything with the previewed screen?
Ideas?
