Resource don't appear on the search window when available

Hi

I have this weird problem. We upgrade our resource database to template 6.x

Every morning, when a user try to book a room it doesn’t show up on the search window, even when the resource is available on that specific time. (new reservation → Search)

Then I have to open the room resource document, edit, refresh (f9), save and close and then it works fine.

It’s something happening overnight I think.

This is an cluster environment (clubusy.nsf)

Any clue that would help me?

Thank you very much
