I've got an application that contains a Crystal Report.  My o/s is
Windows XP, the app connects to SQL Server 2000 and all of the code
was developed in VB using Visual Studio.NET

When I view the report using CrystalReportViewer in a browser window,
all is fine.  The report contains a drop-down list of various export
types, one of which is Microsoft Excel.  When I attempt to export the
report, I get the following error...

Error in File C:\WINDOWS\TEMP\temp_93214fbc-34ef-4340-895d-76acc50cc8f1.rpt:
Access to report file denied. Another program may be using it.

Another program isn't using as, at the moment, the app is running on a
stand-alone desktop.

What is causing this problem and how do I fix it?  If someone has some
code they would like to share to solve this problem I would be very
grateful.

Thanks!
