Something I did recently caused the title bar in Windows Explorer windows to display only the first letter of the path. Thus, the My Computer folder displays with the folder icon and the letter M only. Any folder on the H drive shows the icon and the letter H only, etc. etc. Even worse, the taskbar icon for the folder displays similarly - thus, if I have two different folders on the H drive open in different windows, the task bar buttons look identical. I would be grateful for any ideas on how to get the regular full path name displayed again (and yes, the Tool/ Folder Options setting to display full paths has been correctly set (and reset and reset).
TIA.
