Filtering based on check boxes can be an arduous process. It's automatically paged, and the master checkbox on top still behaved erratically.

I'd propose to give the OLAP Grid an attribute which defines the number of checkbox options before the filter becomes paged (which should be independent of the number of check boxes shown per page).
I'd also like the master checkbox to behave consistently when paging is switched on/off. Right now, e.g., if you uncheck the master check box and switch paging off, all check boxes that were off-page before appear still checked.
