How do I make mouse scroll wheel work in excel

Q: 
Mouse SCROLL WHEEL works in all other office 2007 products but not in Excel.
Is there some hidden setting to make this work?

A:
I was having the same problem. To fix the issue:

1) Goto Control Panel > Mouse> Wheel Tab
Note: This may vary depending on your version of Windows OS.

2) There should be an Exceptions button or tab there.

3) Give a name of your choice and Browse and add Exel.exe. Click OK.

Click Apply and lastly click OK... you're done!
