MMB Not working

I know this is has been asked before. I searched Google, A little through the forums etc…Sorry for repeat.

I have a generic three button mouse - no profiles etc, windows 7…

Was working just fine.
Middle mouse button stopped working when i switched to a browser and back.
Works still in chrome, explorer etc… gives me arrows and lets me scroll up and down when clicked.
Tried downloading another copy of blender,and it didn’t help.
Tried re-installing the mouse, didn’t help.

The emulate 3D mouse tick works… but i would like to use my mouse button.
Anything I overlooked?

Thanks in advance for community help. I just found Blender, and I am fascinated!

Have you tried emulate 3 Button Mouse under File->User Preferences, this worked for me.
