Peter,

Try this:

Add a property allowpagechange to the pageframe (or, if you prefer, the form)

In the MouseDown event of the pageframe:

IF !THIS.AllowPageChange
  NODEFAULT
ENDIF

>I am using a pageframe with 5 "steps" that a user completes. I want to control proceeding to the next
>step ONLY when needed info or proceedures are completed. I added a controllable CONTINUE button
>on each page of the pageframe. I will control the DISABLE option of the CONTINUE button to prevent
