Casey,
I am not sure that EndOfStreamException is throwed from your code.
Maybe it is throwed from uploader internal code.
So you can just do a test :
protected void ajaxUploader_OnFileUploaded(object sender, CuteWebUI.UploaderEventArgs args)
{
Common.Utility.ProcessUnhandledException(new Exception("My Error"));
}
Please confirm it.
Regards,
Terry
