Had one of the above a coupleof weeks ago, and it is a good all round mouse. However, one thing that is annoying me, is the fact that when reading in here for example, and the mouse is not used for a few seconds, it goes into sme sort of sllep mode to save the battery. When this occurs, I find I am unable to use the buttons or the scroll wheel unless I move the mouse. There is a delay when first moving the mouse, and I was wondering if this was "normal" behaviour for it, or if there was something wrong with it. According to the blurb, there are meant to be some sensors in the mouse that detects when your hand is on it, and should take it out of its doze state. This does not appear to be working.
I have put in fresh batteries.
