Two things.<br>
<br>
1. We have something similar right now to do with Crystal Reports.
I fairly sure that I have found the two problems in it. One is that
callback from a dll is into a nested procedure with local variables and could
be called after the object has been destroyed. The other is to do with
strings. The more strings we pass to the dll the faster the crash.
Basically memory/stack/registers are getting trashed leading to nonsense errors
and even the app just disappearing. <br>
<br>
2. Running out of resources. Open the task manager and keep an eye
on GDI objects (the worst), User Obects, Handles etc GDI is the
worst. Windows goes crazy, you cant even shut down. Old version of
Nero used to do this. And ODBC driver for MSSQL did/does it too.<br>
