Someone in my houshold installed IE9. Since then I cannot click or scroll up and down on my social sites. I must be IE9. Nothing else has been changed on my labtop.
I have windows 7 if it matters.
If you are using Windows 7, then you should be using IE9 and not an earlier version. IE8 is vulnerable to various problems. Do you have any other browser besides Internet Explorer installed? I would suggest that you always have at least two browsers available to use in case there is a problem with one. You might try Firefox or Chrome or Opera, all of which are probably better browsers than IE.
It is doubtful that IE is the cause of your problems with Facebook.
