the USB mouse works on my laptop, but not in any USB port. But to be sure, I also bought as PS2 port mouse. That doesn't work either.
The curser will move slightly when either mouse is jiggled, but always snaps back to the top of the screen when I stop..
Meanwhile, as I was playing around with the computer, I got a request to "allow access" to an internet website. During this brief window of time, both mice worked. As soon as I clicked on an option, they ceased to work.
This seems to be software related. But I don't know how to correct it, especially since the mouse is necessary to do almost everything.
