No problems here either, what did you do to get it to misbehave?
I'm wondering if it is a insidious virus posted by a very evil mind. Think about it, a virus that takes over the calculator (& posts itself on to other machines on your network) and isn't anything obvious for AV to find. It sits there doing nothing until the bunch of salesmen in a business, or MPs, go to do their expenses when mayhem ensues.
