Thank you for the welcome, CharleyO. ;D

Ooops! I forgot to tell you that I have a regular ole PS/2 mouse with a scroll wheel. It’s the original mouse that came with my HP computer.

I have now uninstalled Avast ( :frowning: ) and my scroll wheel still isn’t working. There were a few entries in the registry that wouldn’t delete after the uninstall. Is there a clean-up tool I could run to remove these?

I will have a little time to work on this today (not much), so if anyone has any suggestions for me, I would sure appreciate it.
