Wireless key board and mouse problem. So just within the last couple of days I've encountered a problem with my Logitech wireless keyboard and mouse on my desk top computer. The key board still works fine, but the mouse has become increasingly slower (sluggish) in its tracking so much so that while once the mouse pointer would move from one screen edge to another within the confines of tracking on my mouse pad, not it requires repeated lifting of the mouse to move multiple times across the mouse pad. I thought of low batteries but changing out the batteries for new ones did nothing to improve things. Nor did adjusting the mouse speed in the Settings menu of Windows 10. Mouse just getting too old? I've had the mouse and key pad for about 8 years now.
