I get it in both Firefox 3 and IE 7. If I upload a small file (less than 200MB) it works perfectly. The strange thing is that the point where it breaks is never the same - usually though it's somewhere between 300-400. 

Hey Eric,    We've had another user contact our helpdesk with the same issue.  We offered uninstalling Silverlight as a workaround and his IE started working but in both cases their Firefox no longer worked.  Both were running Firefox 4.0.1.  Here in our office Firefox 4.0.1 works fine with the ...

Geoff,   Glad to hear you have fixed that issue.   Silverlight just reports NotFound for every http error.   And our code have improved for many conditions of server side error.   But there would be some unknown condition which our code is not able to catch.   If you get such problem in future , please check ...

In the standard dialog example, Cute Editor uses showmodaldialog function in IE. We think silverlight has some problems in showmodaldialog. This cause silverlight is not loaded correctly in showmodaldialog. So the Flash mode is used. Since silverlight can not be loaded correctly, so UploadType=''Silverlight'' will trigger an ...

Hi,   We have fixed this issue.   But need developers to do something for it.   Please check my thread:   KB - Uploader recent changes , SSL,NTLM etc   Regards, Terry
