Ever think maybe computers just don't like you.

A month or so back you were moaning all over CompuServe and here because 
you couldn't configure your Packard Bell to run Windows. You tried to 
blame Digitalk because you don't understand Windows. Now your having 
trouble configuring memory again and blaming Parc Place. 

I bet QKS is real excited about the prospect of getting your business. 
People like you are the reason companies charge for Support these days.
