I like having an Owner - (But could if necessary
have no Owner).
I want the Component initiate the free in a
non-static method (eg OnExit, OnClick)
No longer referring to the variable - that is not
a problem.
This is all just in the main (only)

My understanding is:
1. If a component has an owner then the owner will try to free it during its
destroy method leading to an access violation if it is freed elsewhere. So
if you are explicitly

Yeah, I would be hesitant too.
WRT forms however, what you can safely do is call Release
(which is introduced on TCustomForm). This will free the form, but only
when all event handlers, etc. have finished processing.

What is the best way for a dynamically created

Explicitly free it when you are done with it (maby add it to a list?)
or set its owner to something valid so when the owner component is freed the
dynamically created component will also be freed.

But I want to self Free - ie immediately after
executing its event it frees itself (eg OnClick).
