Can I Stop Non-List Fields From Scrolling?

Normally any field whose contents extend beyond the visible bounds of 
the object will be scrolled in response to a mouse scroll wheel.

The rawKeyDown message is sent when the scroll wheel is used, so you can 
trap the appropriate values (65308 is "scroll down" and 65309 is "scroll 
up") to prevent scrolling:

on rawKeyDown k
   if k is not in "65308,65309" then pass rawKeyDown
end rawKeyDown

But maybe even simpler would be to remove the empty lines from the 
bottom of the field text.
