I'm using Delphi 4 C/S. Interbase 6.0 and IB_Objects 4.2 Fn.

I have a IB_Query OnActiveChange event which simply does that
quGen.Active := quFam.Active;
quEsp.Active := quFam.Active;
quCompra.Active := quFam.Active;
quOrigen.Active := quFam.Active;

Where qu*Something* is the IB_Query for every dataset involved. There is
no code for grid events.

When I run the compiled program without Delphi simply nothing happens;
after 2-3 seconds, the program closes without any message.
If I run the program from Delphi a message appears saying " Project
MyProject.exe raised exception class EStackOverFlow with message 'Stack
Overflow'. Process stopped. Use Step or Run to continue.

Does it help in something the information?

Thanks.
