We are using the AjaxUploader but are receiving Silverlight errors when uploading files. This is happening in IE 9 with version 5.1.10411.0 of Silverlight. It's strange becuase if you try enough times the file will eventually upload.

The error that we see is Silverlight The upload task is interrupted!

Does anyone know what could be causing this problem? Originally we thought it was version related but this is the latest version of Silverlight.

Thanks
