They have already released a fix for the Logitech mouse and that was also for this specific issue where the scroll feature does not function. It is there on our website but is not applicable to the mouse that you have. However as it is a known issue so very soon a fix might be in place.
So, may they will come up with something,, but in the meantime I would like to do what you did. How much trouble would it be to list for me a 1,2,3 list of what to do. Some of your description was a tad over my old head.........Thaks! kw
