Crystal Reports View seems to hang when trying to Export a report

[Former Member]

We have a web app that creates a report using CR without any problems.  When I run the app from Debug mode in VS2010 and try to Export the report, everything works fine.  However, after the app is deployed and I try to Export the same report, it appears that the browser hangs.  I get the Export Diaglog box but am not able to choose any options or set the pages.  Running Task Manager shows the iexplore.exe taking 50% CPU.  It seems like it is in some kind of loop because the CPU Usage stays around 50% and I have to kill the process.  I let it run for over 10 minutes and it never stopped.

Here is what I have:

Dell laptop running Windows XP SP3

Visual Studio 2010 V10.03.40219.1 SP1Rel

Crystal Reports 2008 Runtime V 12.2.0.290

ITSM Crystal Report Plugin V 11.5.0.0

SAP Crystal Reports Version for Visual Studio 2010 V 13.0.1.220

Here is what is in the web.config:

Make sure you are updated to SP 3:

http://scn.sap.com/docs/DOC-7824

Do not use SP 4.

If that does not help, check the Event Viewer. If that does not help, use Process Monitor, see if the logs tell you anything about what is happening during the run of the report.
