[LIVE] Can't dismiss notifications with remote.

Hello!

I've got a bit of a problem with my XBMCLive (Dharma) setup at the moment. Occasionally, for whatever reason, XBMC will pop up a notification on the home window (eg. 'Script Failed'). This is normal. What is not normal however is that I am unable to dismiss this notification from my remote. I have to either dig out a spare keyboard and plug it in to press escape, or SSH into the box and sudo up a reboot. As long as this notification is onscreen XBMC won't accept any input to navigate menus etc.

Now I'm sure this is simply a problem with my remote.xml keymap, but I can't figure out how to fix it. I can't find a context for it in the keymap and I have been unable to find a solution with global keys.

Can anyone suggest what command I need to dismiss a notification?

Thanks in advance!
