Opening files creates duplicates!

Okay, this really has me stumped. I have my applescript studio application and for the most part it all works fine. I can drop files onto a window and it does its thing with them. I can drop files onto the icon in the dock, invoking the open handler and doing the same thing with them. However, when I drop files onto the app’s icon in the Finder it first duplicates the files and then passes the duplicates to the open handler. What the hell??
This happens even after I remove the open handler entirely. It’ll throw an error message but still duplicate the files. I have two test machines, 10.3.9 and 10.4.10 and it happens on both of them. Has this ever happened to anyone else? Does anyone have any suggestions? My searching turned up nothing on the matter.

Ha, I feel like an idiot now. Turns out there was good reason for creating duplicates. The particular files I was using were flagged as Stationery :smiley:
