This handler is in my standard library stack used by most of my projects:
command enableScrollbarIfNeeded pFldName
if the formattedHeight of fld pFldName > the height of fld pFldName then
set the vScrollbar of fld pFldName to true
set the vScrollbar of fld pFldName to false
It's worked well for me.
