I am trying to examine an item that is over 3 million characters in length.
When I look in the expression box I can clearly see the start of the item.
If I use the left and right arrows to move the item to the left or right this works fine.
But if I use the scroll bar this does not work at all.
What I see looks like characters overwritten with an almost solid line of black.

Environment is Ubuntu 8.0.4.
