+    Quasi-Modal Mode Explained:
+
+    The gtk calls in wxDialog::ShowModal() cause event routing problems if that
+    modal dialog then tries to use KIWAY_PLAYER::ShowModal().  The latter shows up
+    and mostly works but does not respond to the window decoration close button.
+    There is no way to get around this without reversing the gtk calls temporarily.
+
+    Quasi-Modal mode is our own almost modal mode which disables only the parent
+    of the DIALOG_SHIM, leaving other frames operable and while staying captured in the
+    nested event loop.  This avoids the gtk calls and leaves event routing pure
+    and sufficient to operate the KIWAY_PLAYER::ShowModal() properly.  When using
+    ShowQuasiModal() you have to use EndQuasiModal() in your dialogs and not
+    EndModal().  There is also IsQuasiModal() but its value can only be true
+    when the nested event loop is active.  Do not mix the modal and quasi-modal
+    functions.  Use one set or the other.
+
+    You might find this behavior preferable over a pure modal mode, and it was said
+    that only the Mac has this natively, but now other platforms have something
+    similar.  You CAN use it anywhere for any dialog.  But you MUST use it when
+    you want to use KIWAY_PLAYER::ShowModal() from a dialog event.
