Equation Balancer

I've produced a new Smart Notebook file to help with balancing equations.

The atoms at the top have been infinitely cloned so you can drag down as many as you require to show how many atoms there are on both sides of the equation. The arrow and plus sign can also be cloned.

You can download the file from the Think Bank website here. Look in the chemistry section.

I'll make versions for other boards soon. I did try making a Lynx version to test the software, but it kept crashing every 2 minutes so I gave up in frustration.
