It flickers because you try to execute the handler continuously. A solution
might be using the mouseUp handler:

on scrollbarDrag
  put the thumbPos of me into field 1
end scrollbarDrag

on mouseUp
  set the thumbpos of me to round(the thumbpos of me)
end mouseUp

It then will only snap when released, but it may be acceptable.
