No, the hScroll prop is still false, you are just detecting and using (diverting) the information that the scrollerDidScroll message would have used to set the hScroll, but it never gets set.

This is the handler:

on scrollerDidScroll hOffset, vOffset // Scroll or Swipe Detect //
   if the hScroll of group "scrollArea" <0 then ##-->> Detects the Horiz swipe <<--##
   else if the hScroll of group "scrollArea" >0 then
   end if
   set the vScroll of group "scrollArea" to vOffset ##-->>  Scroll the field vertically <<—##

end scrollerDidScroll

It is just a workaround, and it’s not perfect, but may keep you going until the main problem is fixed.
