Hi,

Try cleaning the lens with lint and a mild detergent or isopropyl alcohol. In a normal environment the lens can get striations that fill with dirt and interfere with the signal.

Go slow and the signal is clear enough to be read, go fast and it is not.

I have encountered this problem in design offices.....might be an idea to treat yourself to a Razer Boomslang and only use that one for gaming?

Just a thought?

Cheers
