Chalkboard Math – Chalkboard Math Review

I clicked on the "about" button and can't get rid of the window now to use the program... I clicked on it again to see if it would close and it only enlarges the drop shadow around it with each click. Closing the app and reopening doesn't work to remove it either, so I guess I will delete the app now. Thank you, anyway. Follow-up on previous problem with the about window not closing: We noticed that if you keep tapping the screen the drop shadow gradually fades until the box closes. A little quirk... We like the program and will use it, but it would be better if children could write on it with their finger instead of having to type the answers.
