Input: This keyboard and mouse worked fairly well until recently.  Now the mouse has gone bonkers.  The scroll key works intermittently.  I have to use the keyboard arrows, or press down on the roller wheel, at which point a funny icon pops up, and mvoing the mouse ever so slighly causes the screen to scroll like a rocket, until you push the roller wheel again, when it then reverts to a no scrolling mode.  It has jst about rendered itself useless, and I will go back over to my old Logitech wired setup, as this keyboard mouse assembly has frayed my nerves and wasted my eyeballs and zapped my productive time like crazy.  There ought to be a law, demanding full documentation of whatever is causing this.
