Hi Roger,

As you know from trying, the 'grab' command doesn't
take the grid settings into account, so you could
either enter an enhancement request in Bugzilla ; or
you could roll your own grab command, based on the
following quick-and-dirty example :
--
local sDragging
on mouseDown
  put true into sDragging
end mouseDown
on mouseUp
  put false into sDragging
end mouseUp
on mouseRelease
  put false into sDragging
end mouseRelease
on mouseMove x,y
  ## only react while we're dragging
  if sDragging is not "true" then pass mouseMove
  ## suppose we have a 10x10 grid, recalc x and y
  put (x DIV 10) * 10 into tX
  put (y DIV 10) * 10 into tY
  ## update the location
  set the location of me to tX,tY
end mouseMove
--

Hope this helped,

Jan Schenkel.
