Hi Jack,

Thanks for the info however simply posting a call stack dump does not
give us enough information to track down or fully understand a problem.

1. Please upgrade your version of ReportBuilder to 14.05 and re-test
your application.

2. If the issue still occurs, we are going to need more information
about what conditions are necessary to reliably recreate the problem.
Does it occur with every report?

3. Once you have upgraded, please try to create a simple example I can
run on my machine using only Delphi and RB components that recreates the
problem. Send the example to support@digital-metaphors.com in .zip
format and I'll take a look at it for you.

Nico,

I'm fully aware that a simple stack dump is not enough. I can't replicate
this issue in my lab but keep on getting it in error logs from my customers.

before I just throw another version, is this an issue you know (or believe)
was addressed in 14.05?

Thanks

-Jack

14.05 fixed numerous issues, many dealing with the preview, so it is
possible that it will fix the problem(s) you are having.

RB 14.05 is the latest release of the product. We no longer support
14.04. It is necessary for you to upgrade to ensure we are using the
same code base so I can recreate any new problems here on my machine.

Please upgrade to RB 14.05 and retest. If you still get the same
behavior, please either send a simple example I can run here that
demonstrates the problem or provide me the exact steps I can take to
recreate it on my machine. Send examples in .zip format to
support@digital-metaphors.com.
