A user on our website is receiving a message from Windows Internet Explorer when they attempt to upload a file (via Ajax Uploader).  The message reads,''SLM Error:12029''.  What does this message mean and what can I do to resolve it?   Thanks for your attention to my problem!

I am getting error: Server side exception, failed to upload xxxx.wmv Debug Information: System.UnauthorizedAccessException: Access to the path 'd:\inetpub\domain.net\www\UploaderTemp\uploading.3a99108b-fdb9-ed70-1459-4b50f820cc63.3a99108b-fdb9-ed70-1459-4b50f820cc63.resx' is denied. at System.IO.__Error.WinIOError(Int32 errorCode, String ...

It works fine when I am using IE - the browse file window appear when I click the ajax uploader button. Is it a known issue that a classic fileupload control appears after clicking the ajax uploader in Firefox, Opera and Safari?
