Hardware not functioning properly is most likely caused by driver issues.
The following is a link to a Microsoft article for troubleshooting keyboard
problems:

Oftentimes, hardware issues can be resolved by installing the latest
drivers, if any are available.

I forgot in last post that I tried all above before; MsKey do not show
that Calculator key is even pressed. Also, I can't find any newer
drivers than those on Windows Update / IntelliType Pro 6.1.
