Delphi 2/Reportsmith w NT4

Can anybody tell me, please, whether Reportsmith
(in Delphi 2.01) is supposed to work with Windows NT 4.0 Workstation?

I am trying to use the Delphi connection type, with a simple report, a datasource, and a single table all contained in a data module.

The report runs OK, but when exiting from the program, after running the report, I always get
"Exception EExternalException in module xxx at 77B4xxxx.  External exception C0000008."

Is there a way around this?  Is there a patch for Delphi?  Are there 4?

Are there any other known problems or limitations with Delphi 2 under NT 4?  (I am using Delphi 2.01 Developer).

Many thanks for your tips ...

Ken Travers.

I get that message too, but only when I'm in Delphi running my app.  I have narrowed down the problem to be that if you shut down reportsmith before the app, the app tries to close down the DDE connection that now doesn't exist because Rs-Run is no longer active.  When i run my app outside of Delphi, it works just fine and there is no exception message.  Remember that Delphi catches all exceptions (even the silent ones--try aborting a database from inside Delphi---shows the exception even though it is a silent one that the user will never see).  So I think it is just delphi doing its job.  Try running the app outside of the IDE and see if you get the same problem.  Also, try once when you close the report program before closing the app and once where you leave it running till after closing your app.  You will probably see the error message for one and not the other.  I have been ignoring the error because my users will never see it.

Hope that explains it (if you like my comment, ask me to post as an answer and I will),
