Hi Christopher, Quite honestly, it's been a bit since I used this computer, which is the only one I use with Linux.  That is only a function of convenience as I have an old windows based desktop that meets my general needs.  I was prompted by your email to switch machines, and shortly after booting I received a message asking if I wanted to update my programs, which I did. Since then I have been using Ubuntu and haven't experienced any problems, so i can't respond to you with an example and can only assume that it has been resolved.  I'll persist and if it happens again, I'll send you a picture.  If the problem doesn't reappear by the end of the month, I'll change the status to resolved and send you an email to let you know. Thanks for your help. Jonathan From: Christopher M. Penalver
