On my 1 month old N800 (OS2008), approximately every 3-4 times I press the scroll down function on the D-pad, some programs I am using will continue to scroll all the way to the bottom unless I stop it by pressing the scroll up button. Doesn't seem at all related to how I press the button but won't do it if I quickly press, only if it's been at least 4 seconds between presses. Never noticed it happening scrolling upwards. And it seems to be getting ever more frequent. Talk about frustrating.

First had this happening when using FBReader with the D-pad up/down configured to scroll by page. Thought it was probably a bug in FBReader but now I have it happening in the browser window too which I've configured to web page up/down.

I wonder if this is likley to be a hardware problem, an OS2008 problem or something related to my configuration of the scroll functions?
