I had a message come up which read:
an exception of class OutOfbound Exception was not handled.
Could you tell me what this means, please :?: :?:

I have seen this error a few times when I tune to the extreme top frequency of a band. For now, I avoid forcing the tuner to the far right. This problem will be fixed in the next update.

This same error was sometimes showing in the beta 0.9x versions but it has been fixed. If you are using a 0.9x version, download the latest version from your account page.
