Does anyone know if there are protocol differences between CLX and XLIB
clients?

I assume that the packets sent from a client to the server are
supposed to be identical, and it shouldn't matter if the client is
written using CLX or Xlib.  However, one of our servers will run
Xlib-based clients, but not CLX-based clients.  We know that it's not
a problem with allowing a connection from a certian host, because we can
run xterms and xclocks from that host, but not CLX applications.  The 
CLX client hangs in OPEN-DISPLAY, which is supposed to be similar to
Xlib's XOpenDisplay, which works fine.

Since this happens on only one server, I suspect the server.  However,
I still wonder if there are subtle differences in what the two send to
the server, or if there are differences such as packet size or defaults.

Any e-mail responses appreciated.
