[Xmonad] mod events not reaching xmonad

[Bas van Dijk]

Hello,

I have a problem. Often, after a while of using OpenOffice with xmonad
mod key events no longer get to xmonad. When this happens I'm forced
to switch to a console and killall xmonad loosing all non-saved work
in the process. I've also seen this using other applications like
Firefox for example. What can be causing this and do other people have
the same problems?

regards,

Bas van Dijk

P.S. I run the latest xmonad
