Erratic scrolling

Most peculiar problem. Suddenly I cant scroll in any window in IE. If I just touch the scroll button then the window shudders to the end of the page. Just touching the button causes the window to shake up and down. In Google the curser in the search box moves on its own to the right. Cannot type in the box. Am using my XP machine for this post as my main Win 7 machine is unusable on the net.
I have just tried rebooting so far, to no avail.
Any ideas please?

Probably a defective add-on. Tools, internet options, advanced, reset.

Then try this


Tools, Inetenet options, advanced, check box for smooth scrollling

Thank You Richard
Perfect, worked like a charm. As you say probably an add on but cannot trace one that has gone on this morning, PC working fine earlier. Probably never know.
Thanks again

Edit: Tried to rep you but I must spread myself round first. Still the thought was there!

For all the help that you have given, it was truly a pleasure to give you some help.
Dont worry about the rep. I know you appreciate the effort and that makes it all worthwhile.
