[fxruby-users] Detecting existing running instance of an application

Firstly, I'm a bit of an FXRuby-Newby, so apologies if this is simple stuff!
Here's my scenario:
I have an FXRuby app running.
When the user starts up the app again, I would like to be able to
detect that the app is already running, and instead of starting up
a whole second copy of the app, I would like to send a message to
the existing app.
This would come in handy when tying a file extention to the application's
'executable' under Windows. So a double click will load the file into
the existing app, rather than create a second copy.
I can see a few kludgey ways to achieve the detection of the existing app (a flag in
the fox registry, a temp file etc) but actually getting a handle of the
existing app is a bit beyond me. What technique will enable me to do this?
Thanks in advance for any pointers anyone can give me.
