I have an unusual issue with this printing under IE7/8 (likely 6 as well).
My page contains a dynamically rendered graph. The contents of the graph are determined by the identity of the user who visits the page. The page is not available without prior authentication.
The page loads and renders correctly in IE7/8. However, the graph does NOT print correctly. When printing or print previewing, the graph fails to load (the red x appears). I've identified that when printing, the browser attempts to reload the image, but does not send the ASPXAUTH authentication cookie along with it. This is required to generate the image (due to permission enforcement in the back-end).
Can anyone help me identify why IE decides not to send this cookie, and is there a fix? Is it related to IEs known issues with modal dialogs?
