I have some sheets in one workbook that does not get updated when I
press CTRL+ALT+F9.

Some of the cells comes from two add-ins I have. One of them get's
information from a remote server using COM.

I once saw an add-in that would make sure to recalc until everyting was
updated.
Does anyone know what this could be?

Or is there some way I can improve the existing design?
