Hi, the programmers of TVISION:
I recently use TVISION, but find it has a very strange behavior
while I quit my TV app, TApplication seems not to destroy all
other objects which has created for my application.
I must actively to broadcast cmQuit message to those windows
which has exposed on the desktop, so that they could finish their job.
1.
in fact, TApplication should broadcast some useful message such as
cmClose, cmQuit to announce windows on the desktop.
and, cmQuit message for a TApplication seems not similar to other
evCommand.
2.
Due to cmQuit is the most important message which all
handleEvent should take response, user's TApplication::handleEvent
could not use clearEvent, and must pass this message to it's parent
handleEvent. am I wrong?

and because other type of classes do not handle this message, so if
I post cmQuit to a TWindow, It must do clearEvent, so that I know
that TWindow is properly dispose all things it occupied.

if you can enlight me, please directly e-mail to me, thanks anyway.
tony
