Getting "cleartool" prompts to work in Cygwin/XEmacs

My version is: "21.4 (patch 11) \"Native Windows TTY Support (Windows)\" XEmacs Lucid" The "cleartool" application (part of ClearCase) will often present question prompts in normal operation, to confirm certain operations. When I execute these commands in a DOS box, it works fine. However, when I execute this in Bash inside Cygwin/XEmacs, at the point where it would issue the prompt, it just sits there doing nothing. If I then press Return, it immediately emits the prompt message, and then prints (approximately) "Process shell finished", which effectively kills the shell. Is there a strategy I can use to get this to work properly in Bash inside Cygwin/XEmacs?
