I am creating a module where I have wrapped the SQL ReportViewer.  I have got the module working when logged in as the host account.  When I try to load the report viewer as any other account I keep getting a javascript error "ClientControllerdnn_ctr390_ReportManager_ReportManager_ReportViewer1 is not defined"

Firefox shows the error as occurring on this line:

<script src="/ScriptResource.axd?d=xHTp81jTw-_uIz1ETqm5aZEGiJEPbrAxpocLrtq-7U_HgEhO1bK3gu4TUelQhEOm3nyBU3l7_rcmi8dO5gbgh-_as82ym_mz0&amp;t=633147577781063750" type="text/javascript"></script>

I have spent a day searching for solutions and fiddling with various properties.  I know that the ReportViewer will not work inside an UpdatePanel and 
I have set the "Supports Partial Rendering" property to false.  The concern is why does this work for a host level account.  
I have also checked the IIS log and there does not appear to be a security issue.
 
Any pointers would be greatly appreciated.
 
Thanks,
Linda
