I have a pageframe with 10 pages. I added a new page bringing the total pagecount to 11. I set the pageorder of the new page to 6 to position it in the middle of the group. Save and run the form, everything is fine. Open the form to do some more design work and the pageorder of the new page is now set to 7. Reset it to 6. Save, run, design, it is again reset to 7. Leave it at 7, save, run, design and now it is set to 8.

Any ideas on what could be causing it to creep?
