I'm experiencing a strange behaviour of kicker.
I use three panels on my desktop (top/left/bottom), and sometimes a panel 
disappears: if I go to kcontrol -> panels, I find it resized to 1% and
placed in the left-bottom corner of the screen. The other two panels 
continue working perfectly. If I re-place it in its normal position, then
it resumes to work.

This is a very strange issue because
- the panel that disappears is always the "last" one listed in
the "Panels" section of kcontrol
- it occurs randomly
- it occurs on debian sid / kubuntu 6.06 / slackware
- it occurs at different users, with different kicker configurations

Further, if you have just one panel, hitting this problem and don't 
knowing that you can use alt+f2 to run kcontrol and reset the panel 
configuration will cut you out of the K menu, the systray, etc.

I have the same or a similar problem with kicker:

The panel is configured to disappear after some seconds, and to appear again when hitting the bottom.
This works mostly perfect, but every few days the panel doesn't appear again.
I have to go to kcontrol-->panel, change something (unimportant what) so that the apply button is selectable. After clicking the apply buttom the panel reappears.
