It should be called, but is not. Strange.
I tried to change the code to not using Application, DoRun, etc but
the result is same.

I think this is a bug. I not for FPC 3.0. I'm using FPC 2.6.

If no more answers, you should report this in Bugtrack.

I use Interfaces a lot, but not the 'implements' feature.
