The form containing secondary TCppWebBrowser control is a design-time form
which is created
automatically with the following call:
Application->CreateForm(__classid(TBrowseWin), &BrowseWin);
There is no explicit freeing of this form in the source code; at least
nothing I've written. It occurs in what ever default
order is applied do design-time forms.

I'm only navigating to a blank screen ("about:blank") so when the form
becomes visible, it doesn't show the previous contents.
Anyway, whether I navigate to "about:blank" or not the same crash occurs
when the program exits.
