Right, it was a change in the 1.5.x series related to tty management 
code.  I think the changes made to help services run without pop-up 
windows broke XEmacs

I compile my own XEmacs and it does not make a difference.  It also 
doesn't matter if XEmacs is compiled with X support or not.

I have not experienced the problem with fonts, but I do have a problem 
with copy/paste; it stops interacting with the Windows clipboard once a 
subshell is started, unless XEmacs is started from rxvt.  One 
interesting bit of information is that if XEmacs is configured to use 
pipes instead of ttys for subprocesses (setq process-connection-type 
nil), copy/paste works fine.

I've taken several stabs at debugging this problem, but the tty 
management in the Cygwin kernel is over my head.
