When I first bought my HP Pavillion several years ago I noticed that occasionally a odd symbol appeareed on the screen. It looked like two small triangles one on top of the other. I soon found out that when it was operational I could control the rate of scrolling. I never found out how to controll this gizmo but now it is driving me mad. If I happen to be looking at page 400 of a large document, it suddenly takes over and races the page to the start or end of the document. This may be handy if it is controllable but right now I would love to do something to cancell its mad operations. This forum talks about synaptics but I am loath to enter the driver in case it has nothing to do with the problem. I would appreciate some help here.
Let me take a moment to thank you for posting on the HP Support Forums.
I understand that you have an HP Pavilion 20-b020a All-in-One Desktop PC and due to the auto scroll working so fast through a huge document, it makes it difficult to read. I appreciate the steps you have performed and have certainly done a good job.
I would like to know the following information to assist you better:
Are you using the same USB mouse that was shipped with the PC or is it a different mouse?
If it's a different mouse, then do you have the drivers for it?
Meanwhile, I did some research and found a few steps in Windows 10 that should help. Please try the below steps:
Open Settings app. You can either click Settings icon on the left side of the Start menu or use Windows + I hotkey.
Click Devices (Bluetooth, printers, mouse).
Click Mouse and touchpad to see settings related to them.
Finally, turn off the option titled Scroll inactive windows when I hover over them. And if it’s turned off, you can enable the same here.
Thank you ever so much for your rapid reply. I am sorry to say that the info you gave me didn't help. As I followed your instructions, the data that appeared was not quite the same as you suggested. Perhaps my computer was an earlier or later version than you used. I even tried to snip off my version of the page but it would not let me paste it in. I think my version is much earlier. As a resort if you need it I can copy the snip and send it by direct email. That may help.''In answer to your original question; no, my mouse is the original hp version as shipped with the computer. Thanks for your help so far - I look forward to any further help uoi may have to offer.
