I understand your frustration, but being someone who's been there and done that, as the rest of the MTU community tells you to go make the appropriate settings on your computer, I can say without reservation that your problem more than likely lies in that, or a conflict with some other program that you have on your computer. If your problem existed on only certain brands, then you'd have one non-typical to what other users had experienced. Mind you, I know I'm being absolutely no help to your situation, but I think this is one best handled by admin. Be patient, and they will help you through this.
