On Chrome 8.0 the marker is almost in the correct postion, but doesn't line up perfectly either (it's within a page of being correct, whereas FF is off by about 400 lines.

The cause of this problem is that we don't know the client area size of the scrollbars (the size excluding the height of the arrow buttons). The current code assumes the height of a buttons is 17px, and that the scrollbar have one button at each end. Both assumptions can be wrong.

I cannot reproduce the problem in FF.

I was able to calculate/approximate the scrollbar arrow buttons height/width by assuming it is the width/height of the scrollbar. Meaning, the width of the vertical scroll bar is the height of the arrow button.  This code went in a while back (Orion 1.0).

Closing this. Please reopen if you still see a problem.
