on open being called numerous times.

Hi All. Do you know why choose folder would be called 3 times (rather than once) if I dropped 3 files here?

on open of droppedItems
	set myFolder to POSIX path of (choose folder with prompt "Please select a destination folder")
	repeat with anItem in droppedItems
		-- more stuff here
	end repeat
end open

The open handler can be called multiple times if the dragged files have been downloaded from somewhere and still have the quarantine bit set.
