Can't figure out what's going on here, I'm going through and methodically pulling out code but it's still not working.  I've got the latest DDL, I've tried to debug but the code is very cryptic.  The examples on the site work fine but not in the app.  Here's the error code:

 

 

Message: Invalid argument.
Line: 1
Char: 106751
Code: 0
URI: http://localhost:1606/CuteWebUI_Uploader_Resource.axd?type=script&_ver=634801868212512369

 

I appreciate any help that you can offer.

I think I may have discovered the culprit. 

 

I had this attribute: 

ProgressPanelWidth="0" 

along with

ShowProgressBar="false" 

I don't know why these two don't play nice but everything works as it should in IE.  Hope this helps someone.
