Henry, I don't, in fact, run listDLLs on the program that won't open. Just tried it again: listDLLs -d cygwin and it hangs.
Sheesh -- it hangs if I run it with any command-line options (other than /?) or none. I'll report the problem to Mark Russinovich at sysinternals. I suppose I _could_ run regmon and filemon to figure out where the problem is ... but that's a royal pain. They're great tools, but it's hard to grep large quantities of output when one doesn't know what one is looking for.
