When trying to save a .jpg or .jpeg, Safari tries to force .dms extension onto end? Not really the most pressing question, but it's bugged me enough to get an account and try my luck...

When I try to save any .jpg or .jpeg, Safari forces a .dms extension onto the end of it, and there's no other way to save that picture. Usually with most things like this, a solution is readily available if you Google for it, but I couldn't find an adequate answer. It's been like this for months. Sometimes it goes away, only to come back the next time I try to save a picture.
use both then go to the file location and delete the .dms portion. Works for me.
