When I do some scrolling with the middle button, often the page suddenly makes another jump and scrolls down after a short delay. This is very annoying if you just fixated on a sentence and the page moves away underneath.
System:
- Windows 7
- Firefox 10 - tried smoothscroll on/off
- Microsoft Wheel Mouse Optical - driver version 8
Already tried:
- another mouse
- another Wheel Mouse Optical (same problem)
- new drivers
- cleaning the mouse
- about:config -> smooth scroll
