Hi Carl,
 
The terminal emulator rxvt.exe looks really neat in a unix sort of way, but locks up on me from time to time too.  For fewer lock-ups I copied the default start-up batch file for cygwin and edited it for msys.
 
THE CYGWIN BATCH FILE IS:
----------------------------------------------
@echo off
 
rem - Cygwin.bat
 
D:
chdir \Tools\cygwin\bin
 
bash --login -i
---------------------------------------------
 
 
THE BATCH FILE MODIFIED FOR MSYS IS:
---------------------------------------------
@echo off
 
rem - msys_sh.bat
 
D:
chdir \Tools\msys\bin
 
sh --login -i
--------------------------------------------
 
Try that out and see if it works better for you.
