Silverlight Key Events In full screen mode...

Jared my friend is building this video player in silverlight. Nothing new about that :) but I showed me its full screen mode and how he used the key up event from the esc to fix up his UI as he couldn't capture key events from silverlight from full screen mode... cool little hack persay. another way around that is to capture events off the document object and or if you can use the on full screen change event.
