True; here's a link for more info:

The hard part is that under Windows, clicking on another document will
launch another instance of your standalone. Now you might be able to have
each instance, when it launches, check the list of currently running
processes and if there's another instance of your app already running, hand
off responsibility to it (via DDE, socket comm, or other inter-app comm),
and then quit.

Just my $0.02,
