I have Windows XP Pro installed on my PC, and I have tried two Wireless Natural Multimedia Keyboards now, both with the same problem.
If I press the HOME key, nothing happens, but if I press the CTRL+HOME or SHIFT+HOME, the result is as expected.
This does not happen on another PC with XP Pro installed. My regional settings are English (New Zealand).
Does anyone know how I could troubleshoot this or why it would be occurring?
