Keyclone Bug

I have a bug with Keyclone.

Im running it with Vista 64 and it works fine for the setup etc, dual boxing is ok too.
The problem comes when it has been left for a while, after a few minutes it becomes unresponsive.

It runs in the system tray as normal but when you try to open it, it will not bring up the menu. left click doesn't work and right click bring up a menu of which nothing works.
It also will not shut down, the only way to cancel it is to go into the TaskMan system properties and manually kill it off. Then restart?

Is this a problem with Vista?
