I have an oldHP XH485 Notebook computer running windows XP. The touchpad has the usually buttons for left and right click, and an up/down toggle button for vertical scrolling. This toggle button has stopped working. I have not been able to find and option to enable/disable it and have found no help at all on HP's web site or on google.
I though it might be a driver problem but the only driver on the computer is for a standard mouse. Does this control the touchad as well or am I missing the required driver? Or is it something totally different?
