[AccessD] Class Rebuttal was: Basic Unbound Form ...

A class object with custom events.  If you want multiple objects to 'see'
that/those event(s), then you have to declare it globally.

Putting it as a property of a form and keeping that form open is just a
hackneyed way of creating a global variable. (And is pretty stupid, because
if that form isn't needed, it's a waste of resources to keep it open for a
class that could be kept open on it's own.)

I'd be interested in seeing this instance where an unprotected global
variable has to exist.
