Can't use mail-lib pop3 on Windows NT or 2000

This bug report will be sent to the XEmacs Development Team, not to your local site managers!! Please write in English, because the XEmacs maintainers do not have translators to read other languages for them. In XEmacs 21.4 (patch 3) "Academic Rigor" [Lucid] (i586-pc-win32) of Thu May 17 2001 on SHALOM configured using `configure UNKNOWN' Please describe exactly what actions triggered the bug and the precise symptoms of the bug: I'm trying to use gnus 5.8.8 with the option pop3-leave-mail-on-server to leave mail on the pop server. This requires using the pop3.el from mail-lib. However, I'm getting errors in writing the .uidls.old file that pop3.el uses to keep track of which messages have been read. At the suggestion of Simon Josefsson, I tried this simple experiment, which *did* give me an error: Simon Josefsson <jas(a)extundo.com&gt; writes: [...] This gives me: I/O error: No such file or directory, d:\HOME\foo.old but it *does* create foo.old! Weird. Any clues on this? I get similar errors when I try to use Franklin Lee's epop3mail package, though this works flawlessly with gnu emacs 21.1.
