Ya, tried that and it doesn't work for me.

To give an exact description of what I'm doing, I have an editor. On the
left is a gutter for line numbers, etc. If I drag along the gutter I select
full lines in the editor. If the mouse Y extends beyond the top of the
gutter I scroll the editor up, if it extends beyond the bottom of the gutter
I scroll it down.

If I scroll down, there's no problem. Everything works beautifully. But, if
I scroll up, no matter what I do it will never scroll the editor field up. I
can put the scrolling before the selection or after the selection is made.
Either way if confines what's selectable to a single "page" of the editor.
