I use Logitech Harmony One (as a MCE keyboard) and Logitech K400r wireless USB-keyboard is attached to the computer.

I'm experiencing some weird behaviour after using mediaportal for a while. Remote controlling the system with Logitech Harmony stops; can't navigate, both the remote and the keyboard stop functioning and when I return to desktop and click on start-button, the run -field (in which I can type commands) is filling with # -marks. I can't stop it and the system seems to produce them all by itself.

I have to reboot the system and after that everything works for a while again and then it happens again. I've run windows own system checks and memory tests and they passed.

THis is making me absolutely crazy...
