I am running Ubuntu 10.04 with dual monitors with a nvidia GeForce 8400GS. Everything is working fine but I have a nuisance that I can't figure out how to fix. On the primary screen on the Gnome Panel it shows all my open applications. I currently have VirtualBox, Firefox, and 3 Terminal windows open and they show up on the panel. I can minimize and maximize,etc from the panel bar. This is my issue. If I move say one of the Terminal sessions to the second monitor it disappears from the primary monitor's panel bar. If I click the hide all applications and show desktop icon there is no way for me to reopen just that terminal window that was on my second screen. I noticed this when I moved my Firefox window to the second screen and minimized everything with the show desktop icon. I could not maximize Firefox cause the application was not listed on the panel. I had to kill Firefox and relaunch. I hope I am describing this alright but if you need more details just let me know and I can try to describe anything that is cloudy a little better. I know there has to be a setting somewhere where I can change this behavior but I don't know where to look.
