message app icon

Probably not a big deal but lately I am having an icon "message app" appear in the task bar at the left side of my screen, window XP home. It is a large icon the size of the icons that appear in that task bar when a program or folder is open. It cannot be activated by clicking. There are no actions available when right clicking the mouse. It's just there. The only way I can get rid of it is to restore my computer to a time when it wan not there. Any ideas what it is. I have all message applications inactive.
