Hi i have a thin black vertical line that flashes on the side of the screen. Its not there all the time. I think it depends on the website. Its not there as I type this out, but it always appears when i am on facebook. It is usually there when I check emails, but not alway the whole of the screen, sometimes just a small section.

Anyone got any ideas what it could be? and of course what i can do to stop it?

F7 toggles caret browsing mode on/off. The blinking cursor indicates caret browsing is turned on.
So she pressed F7 and it's gone!
