This happenes nearly every time I run ubuntu for longer than a few hours: the vertical list of icons on the left side of my screen stick together toward the bottom. Sometimes I can get then to move, to seperate, usually not. I am a CLI type and a work-around is to simply type the name of the program I want to exec in my xterm or Konsole. Is there any way of "un-sticking" the icons? ---this has been happening for years.
