Windows 7 Pro, SP1
I have several PDF files on my desktop. They show up with the standard Adobe PDF icon most of the time, but occasionally the icons change to show what looks like the first page of the document (I don’t know why, and I can’t identify that I’ve done anything to make that happen).
If I create a new folder on my desktop, and move (or copy) the PDF files into the new folder, they show up once again with standard Adobe PDF icon. Moving the files back onto my desktop retains the Adobe PDF icon (at least, until the next time it happens, which may be several days or more later, not predictable).
So any idea why this is happening?
