Strange panel behavious

Sat Jul 24 02:03:40 CEST 2004

Here is a bt with absolutely no plugins, just four move dimples. An
plugin was never added - I just hit cancel everytime.

I'm running slackware 10.0 gtk 2.4 and pretty much stock all around -
well, a 2.6.6 kernel. I doubt that it's my environment, but if two or
three more people chime in with Works For Me (tm) then I'll happily
blame the box.
