Re-creating c\
rograms\morhpeus\my shared folder has worked! Not only have my disappeared Morpheus d/l's reappeared, so have my disappeared Grok d/l's!
The completed files were nowhere to be found before, so they must have been stored in some other format in some other folder during their 'disappearance' (as the dats were no longer in My Grok shared folder).
Thanks for the help, Indy.
BTW I'm still getting d/l'ed MP3s being double listed in My Grokster window. Anyone know anything about that?
