I have an unresolved SPR (24092) where a CE7 device either renders a blank white screen or does not render a page at all.  In both cases, the page is in the device as pressing F5 will render the screen. I had a Microsoft case open with not luck on getting the issue solved. If you run across this and have a stand alone reproduction method, please let me know so we can re-open the SPR and MS case 113053110481662.
