What OS are you using? What version of graphics driver are you using? Please try the Intel (R) Driver Update Utility to determine if you have the latest graphics driver installed. It can be found here: http://support.intel.com/support/graphics/detect.htm
I am having the same problem.
My details are Windows Vista Home Premium and my Driver is 18.104.22.1684. I used the link to ID it.
Thanks for you help.
