I upgraded from Windows 7 to Windows 10 on my Acer Aspire 7750G-6645 Notebook computer. Everything seems to work fine except that the touchpad scrolling doesn't work. The touchpad for this notebook isn't 2 finger it's a up & down band on the rightside of the touchpad that you gently slide your finger over it up or down to scroll. If it's a Driver issue which driver do I needto install because I don't see a Windows 10 driver for the 7750G LAPTOP I have. How do I go about fixing the scroll issue? I'm pretty much just a novice when it comes to dealing with computers so please to sure to type it out step by step. Thx
