I haven't done much with AIR, but anything I've been able to make work with the previewer has worked as exepected when the package was created and installed as a desktop app.
Could you post the .air package to take a look at it?
Hey Michael -
Thanks for your response. I seem to have corrected the error which was tied to a Filestream object that I had opened but failed to close. Once I cleaned up after myself as I should, it seems to be behaving as expected.
The curious thing to me is that it worked fine when run from within Dreamweaver, but failed when run from the installed package, making it a bit difficult to debug.
