Cannot select contexts in IDEA 10.0.2

I select either the filter button in the coverage panel or go via the project settings (same either way) to get to the clover setting dialog. I select the 3rd tab (Contexts) and check the check-boxes 'catch bosy' and 'property methods'. The boxes become checked but the Apply button remains disabled (this is the main issue).

I add a new custom context - and the Apply button is enabled.

I click apply and the check boxes all reset back to their un-set state. The custom context remains.
