Xemacs bugs?? or misconfiguration

Hello: I am using Xemacs version 21.1; May 1999 on windows NT platform. This version rely on cygnuswin32 to run. It works OK but I do have some problem: 1. when I try to print buffer with Pretty-print buffer command in file menu. I got following error message: Printing ... Open output file: No such device or address, //Q/PWE/bhu/C:/TEMP/emacsHdAydt. within the message: //Q/PWE/bhu is my home dir. C://TEMP is the temporary dir in window. How can I solve the problem? appreciate your advice. Bizhong Hu
