I have this issue where the Upload button appears, but when clicked, it becomes grayed out and noting happens -- with IE7.  It does work perfectly fine, as-is, however with Firefox 3.0.  I am using the multiple-files-upload.aspx example...

 

I was able to resolve the issue by making the following change:

 

 

I modified it by adding the UploadType keyword as follows:

 

 

However, the values, "silverlight" and "iframes" do not work.  By using the value, "flash", it now works. 

 

Is this a bug in the software?  How can I make this work using "silverlight"?  Is there some other fix that negates the need for this parameter to be added to the control?

 

Thanks.
