Why is the launcher menu disappearing from the Windows desktop?
It is possible to move the launcher off the Windows desktop behind the Taskbar. When this occurs, you will be unable to retrieve the launcher with the mouse. To access the launcher:
Windows XP: Right-click the taskbar and uncheck the "Lock the Taskbar" option and the launcher will pop back into view on the desktop.
Windows 98SE/ME & 2000: Right-click the taskbar and choose Properties from the popup menu. Now select the check box for the Auto hide option and the launcher will pop back into view on the desktop.
