>>> I think I got this working well.  Basically the way it works now is that use uses DDE to receive the double-clicked filename.  This also gives Pd the filename in full unicode, while "%ProgramFiles\pd\bin\pd.exe -open" is still only ASCII or maybe latin1.  That unfortunately means that if the file that launches Pd has extended unicode chars in it, that file won't be loaded since its handed to Pd using "pd.exe -open".

Then any other new Pd instances just don't register with DDE.  Unlike with GNU/Linux, there is no check whether the current instance should quit since Windows sends the DDE directly, we don't need a tcl program to find the Pd instance and send it a message.

Looks like it's back to the old behaviour. If I double click a file it 
starts a new Pd session. Not that it bother's me really. I mean with the 
drag and drop plug-in is a nice alternative to double clicking.
At least now I can start a second session.
