Confirmed that powerlaunch is the problem. At least version 0.7 is, which was all that was available when I first installed it. I notice that there is now a version 0.82 & 0.83 available, but both of those give me a 'package not found' error after downloading the package & trying to install via apt-get, so I can't even install them to test.

The bugtracker is empty & both the mailing list & the forum just have a few old messages in them. Where's the best place to report bugs? TX
