Win XP Pro SP3. No characters appear with either of 2 good keyboards or On Screen Keyboard, but a "Beep" sound is made. No apparent security policies, keyboard is recognized in Device Manager. I can't get into setup. Left mouse button doesn't always work, mouse is good. I'm stumped. PCSOFT's List Owners: Bob Wright<[log in to unmask]> Mark Rode<[log in to unmask]>
