I'm on an iMac under parallels 8. I wanted to get the center mouse scroll wheel to function for a cadd package. I downloaded a logitech driver and attempted to install it. What I got was no ability to use the mouse. I can see the cursor but it won't select anything. So I cannot select anything on the parallels menu and when it goes to windows 7 I can only use the tab and arrow keys. I cannot use any windows programs at all so it is worthless to me. I can't get my support code either because of no mouse. I think I need to go back to Fusion. Any help? Larry
