Project StepThree is the above prior mentioned StepTwo further developed.

In one of the incident reports I mentioned that the compiled version had intermittent exceptions, which puzzled me at the time.

It has now become evident that when compiled as a classic target everything works fine.

But when compiled as a dot-net target the execution fails with some exception prior to displaying the application window.

This message has the EiffelStudio trace information and screenshots. Hope this helps in analyzing the issue.

Project files also included.
