This will give the sequence above. Not sure I get this. If you are performing non-UI-related computations in your "Object" (I second Daniel's remarks on your choice of nomenclature, btw), then these will happen on the EDT. But they should actually be happening /off/ the EDT. So it seems to me either you are busying the EDT and lagging the app, or it's really just a laptop warmer. Perhaps another example would be useful. -- DF.
