This is the core changes you made:

Problems:

This appears to cause it to scroll 2 pixels at a time in the UP direction
(fast but not smooth, and fixabable by turning '1343' into '1344'), but it
doesn't work at all in the DOWN direction (nothing happens).

So, what I did was change line 4 to say:

  set the vScroll of fld 1 to ((the vScroll of fld 1) + 1345) mod 1344

...which makes it work, apparently correctly because it doesn't jump or
anything. I guess it starts it going down (in the correct direction for the
mouseLoc).

What say ye about that?
