Pokertracker problem displaying hands

[cwar]

I am using Windows Vista (PT is running as admin) and up until this point have been running PT fine, just today it stopped letting me review hands. For example I click on JTs and try and display the hand it just doesnt show up like it would have yesterday, the only thing I noticed is that the it flashes towards the top right corner (where minimize, maximize and close are) when I click the hand.

The only thing I changed was to use a different monitor as my second monitor. How can I fix this?
