You are using TThread.Synchronize.

In a console app, it's likely that somewhere else in your main thread 
you'll need to call regularly Classes.CheckSynchronize to allow the 
actual execution of CallEvent.

In my case, linux server dll called by a 4js 4GL console program (no GUI 
on linux server), I need to call regurlarly Classes.CheckSynchronize 
froml 4gl through function exported by the pascal code.
If I don't do this, the CallEvent is nether called.
