ReportDocument.Close() causes application to hang - solved?

My application hangs on the ReportDocument.Close() method.

This problem is similar to these two posts except that I know exactly what is causing the problem.

ReportDocument.Close fatal

Closing the Report Viewer causes the application to hang

My .net windows forms application uses (CR 12.3 also know as 2008 SP3) and another application on the same machine uses CR 8.5. The 8.5 application is using two CRUFLxxx.dlls. I can see that these two dlls are loaded when my application runs reports even though they are not related to my application in any way.

When I close a report my app hangs. If I un-register the two CRUFLxxx.dlls my application runs just fine but of course the other application is now broken because it needs them. If I re-register the CRUFLs then my application is broken again but the other one is fine.

I have no idea whatu2019s actually going on in the CRUFLs because they do not belong to my code base.

Question 1

Is this a fundamental Crystal problem (old vs. new with CRUFLs) that cannot be overcome?

Question 2 related to 1

Do you think it possible to modify the CRUFLs to make the problem go away?

Question 3

Is it possible for me to do something in my application to cause Crystal to ignore the CRUFLs?

Thanks for your time and expertise.
