Have you assigned application/octet-stream to something in edit\preferences\Navigator\Helper Apps ?

It appears that you are correct, application/octet-stream was assigned to .jpg in that preference. I have no idea how that happened, I didn't do it and no one else has access to this machine. Could a rogue app or web page have done it? I have changed it back, and at least for now, things seem ok. I guess the default is that there are no assignments? Thanks!

yes, the default is no assignments and you can't add this with recent builds. *** This bug has been marked as a duplicate of 189598 ***
