Canon Pixma mp500

Afternoon All,

I'm after some help please -- I have a Canon Pixma mp500. It's a fine all in one printer and does it's job accordingly.

However, everytime I switch it on the Microsoft Wireless Multimedia Keyboard and Standard Wireless Optical Mouse become very unresponsive and slow. Once I switch it off they both work fine again.

It's almost like there is a conflict somewhere! I have un-installed both and tried re-installing them in different orders and with the latest software updates but no joy.

Any and all help would be gratefully appreciated.

Regards,

Pat.
