I have a project with 9 pageframes, and I use alot of 'thisform.pageframe1.page1.enabled=.T. as well as ...activepage=1. It sounds to me like you might have either not covered all your bases in terms of what is active, what is enabled, and what becomes activated when the last field of the form loses focus. Also it sounds like you might want to look at what is enabled/gets focus when each page is initiated.
