The two-finger scrolling works fine when I have a website page open in Firefox, and the page moves smoothly up and down the screen. One issue (being explored in another sub-forum) is the snail-like boot-up time.Īnother seems to me slightly weird. I have just done an in-place upgrade of Win7 to Win10 (v21H1) on my Samsung RF511 laptop, and I'm discovering various problems as I now try to use the computer.
