 I probably should have said "black box" instead of sandboxing.

Well, the App is LC IDE.
the stack is a plugin which uses the external.
I don't use any dialog (I'll check if there is one I forgot in a corner)

Before calling the external, I set some vars,
call my external and wait for the return.
If it's ok then I work with the new datas and basically
redraw an image with the imageData.

Plus, when I have this error, everything works!

The error on the tester computer may or may not be related to this;
I've only this information so far :(

Thanks Trevor,
