When I invoke some program from tray panel, the auto-hide-configured panel besides the tray panel does not hide until the cursor point touches it again. For example:
1) Of course, set the panel besides the tray panel to auto-hide;
2) Run Tomboy Notes and minimize it to the tray panel;
3) Click the Tomboy Notes' icon at the tray panel and choose pop menu item search all notes.
Then the panel does not hide.

It happens to me too to have a gnome-panel that doesn't hide anymore.
Re-setting the 'auto-hide' setting doesn't help.

What does help, is `killall gnome-panel'. Not very elegant, but may save some
frustration.


Thanks.
