Dialog boxes not opening

Anyone else having issues with dialog boxes opening? I have 2.02 build 3. It was working fine, but recently some dialog boxes do not display. Specifically the publish results, the edit competitor, and series properties dialog boxes do not display.

I have completely uninstalled and reinstalled the application with the same result.

I have recently run windows updates, which may be coincident with these dialogs not working.

Any ideas?
