When begin working on a new document in MS Word, I always save it to the desktop and then I choose where to file it at a later time. For some reason, in Lion I have had this thing happen to me on twho separate occasions: I save a Word document to the desktop and then I save the same document as a PDF to the desktop. However, when I close word and go to my desktop, the files are not there. Accessing the desktop folder from Finder yields the same result. If I then reboot, I find the files on the desktop where I saved them after I log in. What causes this to happen? Any ideas? I am about to receive a replacement (late 2011) for my recently purchased (early 2011) MBP. I don't want to restore from Time Machine in case this bug relates to my profile, but if it's a known issue in Lion, I will restore out of convenience and because I am worried about being unable to reauthenticate some of my applications.
