I'm using OWL with Borland C++ and can't get a modeless dialog to use the
keyboard interface.  I've made my own dialog class descended from TDialog
and have tried both of the following lines in the constructor:

EnableKBHandler();
GetApplication()->SetKBHandler(this);

From the (scarce) docs it looks like either one of these should do the trick,
but neither works, alone or together.
Modal dialogs seem to invoke the keyboard handler automatically, so I don't
have a problem with them, but this modeless one is beginning to get just a
little frustrating!

Anyone have any sugggestions?  Any little tricks that aren't in the docs?
Thanks in advance.
