Have not experienced any problems on my Imac if you had one you would be able to check the downloadable information once you had finnished using your Computor, this would give you the insight to know what is going on in your machine whilst you are using it, its absolutly amazing how you chaps have survived so long using inferior equipment without knowing what is being used to attack your user interface, you must change immediatly because I know better than any of you.
Sound familier.
