This is not really a normal situation, but anyway:
1. Left-mousedown on the scrollbar-thumb of a page.
2. Move outside the thumb into the page, while holding down your mouse button.
3. While holding down your mouse button, do a right click -> contextmenu comes up.
4. Move the mouse pointer to the "Select all" option, then release your left
mouse button.

Result:
From then on, the scrollbar-thumb follows your mousemovement, the page scrolls
accordingly.
This should not be happening. In IE6 no context menu is opening in this case.

Another way (quite similar) to get the scrollbar to stick with mousemovement:
1. The window should not be maximized.
2. Left-mousedown on the scrollbar-thumb of a page.
3. Move outside the browser, while holding down the mouse-button.
3. While holding down your mouse button, do a right click.
4. Release the left button outside the browser.

Result:
When returning your mouse pointer in the page, the scrollbar follows your mouse
movement the page scrolls accordingly.

That's what should be happening with us too....

Martijn, can you still reproduce this? I couldn't seem to using either set of steps.

This is indeed fixed, it seems. No context menu is coming up anymore, which is what should happen as mentioned in comment 1.
