Hi Terry,
thank you for your answer but it still does not work correctly with IE7 and Flash10a.ocx. When I hit the "Postback" button and switch the panel and then click on "Upload" then the window "File Browsing has been blocked." appears. How can this be completly be fixed? I mean other multi upload controls like google work perfectly. Can you provide a clean solution?
Also I don't understand your code. Can you please help me how I get your code to work with my code below?
Many thanks for your help!
