Refresh() method by default refreshes only the active page of the pageframe. The refresh() should be called explicitly one way or another when you switch to another page. It is not very effective to write the refresh code manually for every page. It is better if you do it in a pageframe class, or you use another class that being added to the pages will refresh them automatically, when you switch the pages. For example, I posted such class here long time ago: file#9211 "Page Tab Chameleon"

But it does not mean there is a problem with pageframe refreshes. It is just by design. It is not effective to refresh many controls on the pages that you don't see at the moment.
