$frame->Close simply generates an EVT_CLOSE so it all depends what is in
your (or the default) EVT_CLOSE handler.
To remove a top level window from the application, use
$frame->Destroy - but note that as it says in the wxWidgets docs, window
destruction will take place a some point - not necessarily 'now'.
So I would guess that you have misunderstood "$frame->Destroy". Probably
because "Destroy" is an odd name for a method that closes the frame
gracefully after ensuring all events are handled etc. :-)
