Further (mostly negative) information on the problem: Nothing shows up in the Windows System Log when bash exits.
Bash stays open to type maybe half a dozen characters, and can run, say, "ls" before exiting. A reboot didn't help. Another person on the same network has no problems with Cygwin, though he hasn't ugpraded to 1.5.8-1 yet. I noticed that in the cygcheck output I sent, all the DLLs seemed to show up twice, but that may just be because I ran it from C:\Cygwin\bin. --Aaron V.
