The files are retrieved through an ASPX file. This methodology has been in production for 5 years without a single report of trouble.</P><P>The download occurs as a content-disposition of "inline", with content-type of either application/msword, application/vnd.ms-excel, or application/pdf.</P><P>The user has demonstrated (to me via webex) an intermittant problem when automating the .doc and .xls files in word/excel. The problem manifests itself as an error message of: </P><P>Error processing request:Object reference not set to an instance of an object</P><P>This error message is located in a new browser window, where i would have expected the content to appear.</P><P>If the user clicks the link 3 times, it is likely that one of those times will successfully open the file in either Word or excell as appropriate.</P><P>The files can be "saved as", and then opened without any problem. This works 100% of the time.</P><P>Opening a PDF file works 100% of the time.</P><P>The error only occurs when a non-adminstrator user is logged in. </P><P>Configuring the browser to trust the site did not have an effect on the problem.</P><P>Does anyone know what is wrong?Fri, 18 Sep 2009 09:49:37 GMTm6rk
