I have a file with an input sheet where all cells are protected except for
the few that require user input. When I am in this input sheet, the
<CTRL-Page-Down(and Up) keys do not work properly. Instead of moving to the
next worksheet it scrolls to the right (or left) in the input sheet. Is this
problem due to the cell protection in this sheet (it works properly in other
sheets that are not protected in the same file)? If so, is there a way to
correct this?

Thanks!
