Hi GeraldMorris,

Does happens with large file? How about the samll files? get the same issue?

Please try this link http://www.ajaxuploader.com/Demo/Large-File-Upload.aspx?UploadType=Flash, it load as flash upload mode and support large file upload too. Does it work with your IE 9 browser?

And please check the large file upload settings from http://www.ajaxuploader.com/FAQ.htm#16, "How do I handle a large file upload?" and "IIS7 and large files" sections. ensure that the settings are correct.

Regards,

Ken
