unwanted text on desktop of macair after cleaning with Onyx

Thanks Barney for your quick reply. I've had Macs for over 20 years and have used this maintenance app for all that time and never had problems. I have heard that it's not necessary and I don't do it often but the occasional cleaning does seem to clear up space and has resolved minor issues in the past. But this time...well, first time for everything.

forgot to say in earlier post that I ran maintenance again, changed the desktop picture and restarted the computer but the unwanted text did not go away

Thanks Jim. I had errands to do near the Mac store so I popped in and the fellow there did exactly what you just suggested. He sorted it from terminal and now it's fine. Spot on!
