I have a Packard Bell 120 Pentium, Win 95, approx. 2 yrs. old with the standard mouse that comes with PBell computers. The mouse has worked fine until recently. Now when I double-click on the desktop or in any program, it only has the effect of a single click. I have to right click to open any file or program. I have tried the test in Control Panel - Mouse settings and the same thing. I have deleted the mouse in Device Manager and reinstalled - no change. I have installed an identical mouse, that works fine, from another PBell computer and no change. Tried switching mouse drivers and no change. Tried deleting mouse and letting Windows detect it on reboot - no change. What else can I try?
