Used a test laptop with clean install of win7, new install of f/fox 11. no antivrus and windows firewall disabled.
running through home broadband with no other security.
Same result.
Don't worry about it. We've made decision to not use this component and rely on clients installing ftp software for the multiple image transfers. its a controlled cms environment so was always an option for us. this wif it had worked as expected would simply have removed the need for ftp software being installed.
thanks anyway
