Hi everyone, I just purchased a Wireless Keyboard (and mighty mouse) for my mac pro. The keyboard is excellent - the only issue I have with it is that the key "s" sometimes won't trigger until I press it couple of times. It doesn't matter if it was the first thing I press after a long wait. Typing a word like "Mississippi" may require pressing the "S" key 7-9 times to get all 4. I tried the search -- only found results related to the "first" key press may not get triggered which was fixed by a firmware release. Anyone experienced this issue before? PS: My wired Might Mouse worked perfectly on my black desk. The wireless version does not work (mouse cursor won't even move) so I had to resort to getting a mouse pad. Are the lasers and tracking devices that different between the two? Thanks for everyone's time.
