I updated to Mt Lion OS on my IMac about two weeks ago and every time I log on I get a message if I "want to update my Lexmark software". I have a wireless Lexmark Prevail Pro705 printer and it is working perfectly. I select update and after a couple of minutes of searching for the software, I receive a message that the "software can't be found".....any ideas on getting this update message to stop displaying. I've tried at least 20 times to update with the same results....insanity
