Mouse stops; menu appears; stop it?

[misterblue]

Dear all,

Another pain in the eras problem on my laptop. Using a wireless optical mouse, whenever I stop moving the mouse, a dialog box opens which gets in the way. The options in the box are internet ones such - Yahoo, Kensington, CNNfn CNet and Mapquest.

I have to click outside the box to get rid of it and hope it does not appear before my next click.

Help gratefully appreciated,

thanks
