I installed TrueCrypt 7.1 Standard 64-bit on a fresh install of Ubuntu 11.10 64-bit. After finding the application in the dash I dragged it's icon onto the Unity launcher. I then clicked that icon and TrueCrypt's main window opened. I mounted my encrypted file/volume and then closed the window to do some work. To re-open the TrueCrypt window I would normally click the small blue TrueCrypt icon that appears on the top panel. In Ubuntu 11.10 that icon is no longer there. I receive a message ("TrueCrypt is already running.") if I click on the TrueCrypt icon in the launcher.
How can I re-open the TrueCrypt window after it's been closed in Ubuntu 11.10?
