XBMC respond (activity) when buttons on remote are not pressed..

Hello All,

Since a couple of weeks my xbmc setup is doing weird.

When i watch a movie weird stuff happens (About 6 times)..A screen is popping up (like someone presses a button on my harmony 1) when my harmony remote is on the table.
Also when in idle mode (dark screen) it goes back online without using my remote. So , It looks like it responds to keystrokes not being sent with my remote..

I checked event ghost for any activity but cant find any..

Looked on the forum but cant find any good results to fix this problem. Hope someone can help me!
