Editing a droplet with AppleScript

Hi all (again).
When i edit a droplet (building from Script Editor, Tiger), right clic con droplet, “show pakage contents” and I open file “main.scpt” inside folder Scripts of folder Contents of folder Resources (oh, my God, I think in Applescript!).

Afer editi file main.scpt and save, I try to drag something inside (for testing “on open” handler), but often the droplet doesn’t recognize the drag action. I have to duplicate it or to relunch Finder, and after it works fine.

Can I make something more simple for refresh the folder of droplet?

Better open the applet/droplet from Script Editor with cmd-O
