I can't reproduce this one. Does it happen consistently? Does it go away if you right-click here and choose "Restore desktop defaults?" (this just resets docked panel layout - things like ut/plsql manager, sql recall, object palette, etc) ---

Didn't happen again. After a restart everything works as expected. Not sure if it ever happen again. 😉
