I don't think I did use the CD that came with such. I think I went with the software that's available on their website. The mouse settings are where they were originally set at, to my knowledge. And the troubleshooting feature shows it's working normally. :-?

well if it were a battery operated one I would suspect the need of new batteries. Or that it's line of site to it's transmitter receiver was blocked. Have you checked your mouse settings in control panel to see if possibly some settings went awry? Check the surface you have it on, sometimes they do not work well on very shiny or glass like surfaces. What kind is it exactly? brand and type.

Enjoyed your story. It brought back memories of my encounter...I'm going back 50 years. DH was in the army and we were in a teeny tiny apartment in Fort Benning, GA. I was baking Christmas cookies. The apartment was so small, I didn't know what to do with the cookies I baked, so when I was done, I decided I'd set a platter of them in the oven until I figured out where I'd store them. When I opened the oven door, there he was swinging on the rack like he was in a gymnasium. I slammed the door shut, ran to the bedroom terrified, shoved some bath towels under the door and stood on the bed till DH got home. How irrational is that?!!!

Sometimes (often) I would mistakenly bump the Houz up arrow by accident. When using an iPhone or iPad, I just tap once a bit below the black margin at the top of my device screen. This takes me to the very top. If I was to go to a previous screen, I tap upper left of screen and a blue < appears that I can tap once to go back previous screens in the same window. Now, on the two aforementioned Apple devices, does anyone know how to move quickly to the very bottom of a screen? (Other than to thump/finger keep sweeping down past pages. Thanks
