Repeating the same command over CEC

Hi,

I'm running XBMC on a Raspberry Pi (OpenElec).
My Philips tv supports CEC, using its proprietary name Easylink.
With the TV remote, I can scroll through the XBMC menu, but only once in one direction. So if I, for example, click right, I can't click right again, it just doesn't respond. The same for any other key, like OK. So going into menu's I can only go one deep, unless I use another key in between, then OK works again...

I hope I made myself clear, as this is hard to explain.

Does anyone know how this can be fixed?
