For some reason Firefox is no longer letting me scroll using the Pg Up and Pg Dn buttons. I am not sure what changed. When I try to use them they just cause the browser screen to flicker as though it's trying to go up or down and it's causing it to jump so to speak.
I've tested my Pg Up and Pg Dn buttons on IE and it works on there. I much prefer Firefox so if someone can help me figure it out I'd really appreciate it.
Thank you so much in advance.
