"Invalid pointer operation" when closing Data Modeler

Hi!

Is there a way to check the dgp file integrity?
Are there any know limitations on dgp file size ?
Any archive version requirements ?

Mi biggest project has a 2.17MB dgp file. It loads and saves without warnings, but now everytime I close Data Modeler, it raises an invalid pointer operation error and than an AV loop, so I must close it using task manager. Other smallest projects close without errors.

I wonder if it would corrupt the project file at anytime.

Thanks.

Answer is "no" to all your questions, more in a sense that we have to investigate the specific problematic dgp file to find out what is going wrong.

If this is consistently reproducible, are you able to share the .dgp file (you can send it to me via private message if you don't want to share it here) so I can check what might be causing such issue?
