I've mentioned the problem here before, but as far as I know, no one has pinned it down, because all of the Win32 builds from June forward exhibit this behavior.  Thanks for looking into it!  -R.

Subject: [Flightgear-devel] pilot list...

While attempting to hunt down a chat message problem , (no messages displayed from certain players),
I found that the pilot list is always 1 player short , and the "model view" skips that player.
They all appear in ai/models , but num-players is always show 1 less player.
I've been sifting through the multiplay.nas , but thought I'd mention it here in case someone has
already looked at the problem .
