Mouse wheel button stopped working after reinstall of Win7-Solved

***Please disregard the below information and see my reply for the real reason the mouse didn't work***

Hello All, A couple days ago I wiped my laptop drive and reinstalled Windows 7 Home Premium 64. After installing my apps I ran Firefox to surf the web. I discovered that the middle mouse wheel/button would not open links in new tabs when pressed as it had before the reinstall.

I looked for solutions on the web, including this site, downloaded updated drivers for the mouse and installed a Firefox extension that I hoped would re-enable the middle mouse/wheel button. No Luck.

Last night Windows 7 popped up a nag screen that said I had entered the wrong product key and prompted me to enter the correct one. I entered the correct key and allowed the activation/registration to complete. Later, while surfing the web, I reflexively clicked the middle wheel/button to open a link in a new tab and it worked! I wondered why the heck it was suddenly working. I mentally backtracked to figure out what might have changed and the only change was that I had entered the correct product key and registered Windows properly.

If you do a fresh install of Win7 and discover the middle mouse wheel/button doesn't work, check your activation/registration and ensure that you put in the right key and the activation/registration process completed successfully.

Cheers

Follow up correction.

Ok. The middle mouse button stopped working again. I remembered that after rebooting after entering the correct product key not all my tray icons appeared. So obviously the registration didn't fix the problem directly. Rebooting without a startup program running fixed the problem.

I had installed a program called KatMouse shortly after reinstalling Windows. Turns out KatMouse was causing the middle mouse wheel/button problem. After another reboot I clicked on the tray icon for KatMouse which turns it off and the mouse wheel/button worked again to open links in new tabs in Firefox. KatMouse was the real problem.

Cheers
