Pascal,
I wouldn't know "Best" but for my $.02 US --

I create my "application object" in the main program. Others, like my user class, my menu class, etc. are instanciated as needed - in most cases before the first login form.

The exception is any class that is form specific rather than application-wide. In that case, I do an AddObject() on the form.
