Subject: Old kde bug.

There's an old bug reported now and then for a good 4 years that I can remember......the task bar disappears. It would be a good idea if this one was squashed for good. I do have an easy temp. fix, however.
First, it appears to only happen, or for the most part anyway, when you have chosen to hide the taskbar in the personal settings in KDE. The problem is that somehow the kickerrc config. file gets corrupted.....how I'm not sure. Here's what I've done to work around it.
Put the following in your /home/?/.profile file.....at the end.........cp /home/?/.kde/share/config/kickerrc /home/?/.kde/share/config/kickerrc.org
Every time you log on as a user, a copy of kickerrc called kickerrc.org (for original) is written. If you loose the taskbar, DON'T logout, but use konq. to delete the kickerrc file and copy the *.org file to kickerrc. Then, ctrl-alt-del to kill the desktop. Relog into your user account and you should be back in business.
As an alternative fix, edit the kickerrc file, and change "true" at the end of this line to "false" then save the file. Use ctrl-alt-del to kill the desktop and log back on.
Hope this helps those who've been hit with this before.
