Hey guys,

I'm having difficulty getting the Kinect to track at full screen — I can manage static images to display at full screen but motion-sensitive activity is isolated to the standard Kinect 640 x 480 depth camera parameters in the upper left hand corner of the screen.

I tried swapping out all "int" values to match the screen size (or pretty much any size larger than 640 x 480) but always get an error message: "ArrayIndexOutOfBoundsException". Any ideas for how to solve this?

Thanks in advance for your help!
