The UpdatePage() seems to be working now, with no side effects. Big thanks to 
Pm and Crisses!

If you wonder why such a function, what I am tinkering is a functionnality to 
quickly send a sort of yellow-sticky-notes or links-to-wiki-pages to one of 
31 calendar pages. At midnight, pmwiki grabs the current-day page and moves 
its' content into the INBOX page, so the user can easily see his tasks or 
reminders for that day.

It is not at all finished now, neither I know if it will be as usable and 
effective as I imagine, but if someone is interested, tell me and I will send 
you what I have. (I am using a pmwiki installation for a personal notes/todo 
manager.)

Thanks again for your help!

Take care,
Petko
