This is really strange. If I add a product, and upload an image while at it, it gives me a "Save as" page for "product" when I click Submit. If I cancel and click node form Submit button again, the form submits, but the image is not there. If I then edit the page, and insert the product image that way, everything works fine. Very odd.

Please let me know how I can further troubleshoot this one.

Thanks,
Andrey.
