I gave this report a rating of 1, based on the very shoddy, complex example program given.

This is a test case error. Moving the ancestor's code in AfterConstruction to its OnCreate event and the code in the Browser form's constructor to its OnCreate event, I was able to eliminate the access violation. It occurred because reference was made to components that had not been initialised yet.
