Q: mac book air

Relatively new (2-3 months) Mac Airbook running 10.8.2.  Active window flickers approx. every 10 -15 seconds.  Desktop display does not flicker.  Issue is present in Firefox, Office for Mac apps, Preview, Mail etc.  Haven't tried all apps but I am guessing it is a persistent (consistent) problem.  Any advice welcome.

MacBook Air, OS X Mountain Lion (10.8.2)
