I have your control installed on our hosted site and am having a problem with larger files.  I was originally using the UploadType="Auto" but had to change it to UploadType="IFrame" due to a number of browser incompatibility issues.  This site is SSL only and with various broswers I was getting file interupted and not being able to even click the add files button. 

 

With IFrame all the problems seem to be fixed with the execption of larger files.  I can upload mulitple small(<20MB) files without a problem, howver if I attempt to upload a large file (>20MB) it just sits there attempting to start the upload without ever doing anything.  Progress shows:

 

Uploading filename.extension. -KB at -KB/s; - seconds remaining.

 

Any help would be appreciated.
