Hi Tore

for fields you can set the vScrollbar and set its width to 0

For groups this does not seem to work.

A workaround is to put a script like this into the script of the group

---------------------------------------------
on rawkeydown pKey
   put 6 into tIncrement -- change increment here
   switch pKey
      case 65308
         set the vScroll of me to the vScroll of me + tIncrement
         break
      case 65309
         set the vScroll of me to the vScroll of me - tIncrement
         break
      default
         pass rawkeyDown
   end switch
end rawkeydown
--------------------------------------------

mind you this only works if the content of the group is taller than the
group. You would have to set the lockLoc of the group to true.

Above script triggers a "scrollbarDrag" message. If you don't want this add
some message locking.

Kind regards
Bernd
