Oke, no did not tested it in photopost pro. Photopost pro is (after using) not useful for us because the admin is not included in VBulletin, as well as the separated user info (even after migrating with vbulletin). Can I ask who the third party is? So I can contact them with my problem?
Flash10. FF en IE both don't work. May I ask what the flash uploader in your message means? :-)
