Guest LB Posted September 16, 2003 Report Share Posted September 16, 2003 When you use Internet Explorer 6.0 Service Pack 1 (SP1) to view a MIME type file attachment that is handled by a custom ActiveX control, it may take a long time to view the file, particularly if the file is very large. This behavior is different from what you experience in Internet Explorer 6.0 and earlier in the same scenario. Internet Explorer 6.0 and earlier versions create an instance of the ActiveX control before the file is downloaded to the cache. However, in Internet Explorer 6.0 SP1, the file is downloaded to the cache immediately -- before an instance of the ActiveX control is created. For performance reasons, this behavior is not optimal, particularly when you view large files.download from Here Quote Link to comment Share on other sites More sharing options...
