If you are using your Whiteboard and are looking for something cool to play with I can suggest PicLens.
It's a free add-on for Firefox that enables you to view pictures in a really cool way
Check out their website for a cool video displaying many features.
Best of all - works very well with my IR-pen
http://www.piclens.com/EDIT : I forgot to mention that it has right click disabled so it works just fine with your IR-pen
