Try and reload the software first.

If that doesn't solve the problem, go to Remote Central and search in the Home Theater Master Forum. I suspect you might have to find an earlier version of the software. Issues like this pop up when they provide an update to the software.

Give Mike a call at Surf Remote Control (assuming you got the 700 from him). He pretty much knows all things MX-700.

Haven't had the problem, so this is conjecture.
