/* This was originally server.c in the OLE1 Media Player.
* It is here somewhat munged to bolt onto the side of the OLE2 Media Player,
* to get around the fact that OLE1/OLE2 interoperability is broken in Daytona.
*
* The OLE2 interface is Unicode, whereas the OLE1 interface is ANSI.
* This accounts for some, though probably not all, of the horrors that are
* about to unfold before your eyes.

Important Note:
No method should ever dispatch a DDE message or allow a DDE message to
be dispatched.
Therefore, no method should ever enter a message dispatch loop.
Also, a method should not show a dialog or message box, because the
processing of the dialog box messages will allow DDE messages to be
dispatched.
the hacky way we enforce this is with the global <gfErrorBox>. see
errorbox.c and all the "gfErrorBox++"'s in this file.
Note that we are an exe, not a DLL, so this does not rely on
non-preemptive scheduling. Should be OK on NT too.
