I doubt your OS has anything to do with it. I really don't know why it's happening, but the only time I've personally seen it is when I had two psts open at the same time ... and once I got rid of the second one, the duplicate tasks went away ... are you sure you don't have ANY remnants of that other pst? Check your Tasks and Calendar ... are there duplicate entries in there? If you make a NEW task now that you are sure the other pst is gone, does that one show up as a duplicate too? ******************************* Linda F.

My backups are on another drive. Does it matter that my OS is now on drive F: and not C:?
