I am running my reports out of the ReportExplorer, it would seem that if
that I can run a report in preview mode close it down, it works fine, open a
second report in preview mode shut it down an it AV's.

I have been able to ruffly pin point it to TppViewer.Destroy;
especially when

FScreenDevice.Free; // TppViewer.Destroy;
// Down where it does a SendNotify(
// One the of the subjects is TppCustomReport.Notify(
// it is falling over on this line. ppClass #3420
else if (FTemplate.DatabaseSettings.DataPipeline = aCommunicator) then
FTemplate.DatabaseSettings.DataPipeline := nil;

The FTemplate.DatabaseSettings is invalid.
I have wrapped this bit of code in a try except to get around it for the
time being.

Environment..
Running Delphi 6 Enterprise, RB 7.02
Windows 2000.
The application can be hooked to Interbase via BDE and
MS Sql Server via ADO.

    Dave,

    I tried recreating your issue with the \RBuilder\Demos\4. EndUser
    Databases\InterBase\1. BDE demo and wasn't able to cause an AV. Please try
    to recreate the problem using one of our demos and tell me the exact steps I
    can take to cause the error and/or send us a report template that created
    using our end user solution in .zip format.
