I don't know if this is the right category, but.......

this mouse on an ME system now does everything twice. Click to delete an email, it deletes 2. Click to open the browser, it opens it twice. Odd.
Is this a driver thing, or what?

Anyone?

Thnaks very much.

Does rebooting help?

Check your mouse options in control panel. Check the double click speed.
You could try reinstalling the driver to eliminate as a possiblity. It could also be the mouse itself registering more than the double click.

I would try another mouse. If it still happens, you know it is a software problem. If not, it is the hardware.

Did you run your antivirus software? If so, did you find any viruses?

Thanks to all. Re-installing the driver... that's it !
