Catch the boomerang(for attending 'Intel perceptual computing challenge')

Recently, I'm preparing to enter Intel perceptual computing challenge. One of my ideas is a simple gesture game. It's called 'Catch The Boomerang'. Some brief sketches are below.

Users can throw the boomerang by rotating their wrist. Distance of flying, speed and the count of caught boomerang are displayed on the game screen.

Of course, the thrown boomerang will be returned, so that users should catch the returning boomerang by grasping gesture.
I hope to get an opportunity which can attend next stage.

When computer is locked in XP, proceeding redrawing.

During the time that computer is locked in XP, if application's size is altered or do other drawing work, these works will not reflect after the computer is unlocked. Although, it will be changed in Vista or Win 7.

In normal case, it will be solved by managing WM_ACTIVEAPP, but during the time, through executing other program + altering size + redrawing, if z-order is changed, unfortunately other program will be received WM_ACTIVEAPP.

Therefore, the most effective soluting is to manage WM_WCSSESSION_CHANGE.
After checking the WPARAM value of the message is WTS_SESSION_UNLOCK,  doing redraw will be solved this issue.
