Derek,

I guess I don't really know what you mean when you say it does work 
in the inspector, but you don't expect some of your software won't 
work properly.

As a diagnostic, try this script in the scrollbar:

on scrollBarDrag
   put the thumbPosition of me into theNum
   add 50 to theNum
   put the thumbposition of me & cr &  round(theNum) into fld 1
end scrollBarDrag

So that you can see both the thumbposition and the evaluated sum in the field.

This script should give the same results

on scrollBarDrag tPos
   put tPos + 50 into theNum
   put tPos & cr &  round(theNum) into fld 1
end scrollBarDrag
