My first posting.

For a couple of months I've had a problem with my screen scrolling or jumping by itself when I've been using Outlook Express, Word, Excel or when I've been WEB browsing.

I've TRIED just about every program to scan for spyware, malware and viruses but they all keep coming up clean so I don't think there is any infection.

I've also uninstalled and reinstalled Microsoft Office and checked all the connections to my PC for the monitor, mouse, keyboard etc with no obvious problems being found.

The problem occurs whether or not I'm connected to the web.  Other applications seem to be free from the problem.

Can anyone help please?Try UPDATING your video card drivers.

FlameThanks for the suggestion but the problem still remains.  Any other thoughts? Woodford ....... Have you tried changing your mouse ..........? A bad mouse could be causing what you describe.

dl65  Is it a wireles mouse? Does it have more than 2 buttons?

FlameGood morning Flame.  No it's not a wireless mouse.  It is a normal 2 button mouse with a scroller.  Since the last posting I've cleaned the mouse and removed some 'fluff' from the inside.  I'm seeing what happens today but already I've had a few small jumps.

I'm doubtful that the problem is the mouse since if this was the case then every application would have the same problem whereas this is not so.

I've tested a couple of card games like solitaire and the screen remains perfectly steady no matter how long I stay connected.  By contrast when I go into my email or start browsing the web as well as using Excel and Word the screen begins to misbehave.

I'm really baffled - and cross-eyed!!

SteveGood morning Flame and d165.

Having had another go at cleaning my mouse I must say that after a day of testing, the screen scrolling has reduced although it still suffers the odd jump or two.  Nothing like before though when the screen would scroll from top to bottom and partly back up at great speed.

Perhaps the mouse was (is) the problem although I still don't understand why it only affected a few applications.

Anyway thank you for your help - much appreciated.

SteveTry another mouse. Let us know what happens.

FlameThe problem soon came back despite cleaning the mouse.  Yesterday I bought a new mouse and so FAR so good.Hopefully the new mouse will keep THINGS working in good condition... Let us know how it works for you... I'm interested now  

FlameNot all applications respond to the scroll wheel.  A faulty scroll wheel would therefore not affect all applications.Well guys another 2 days have passed without any problems re-appearing.  I'm confident now in saying that the issue was in fact the mouse.  With your help I've learned something new.  Cheers.

SteveI had the same problem and changed the mouse so far (1 day) so good.  Thanks guys.  New to this site and already benefitted!
