Problem with Gnus using 21.2.4x

I've been using the beta XEmacs since Jan 25 (21.2.42). The following problem is repeatable for me: 1. Start gnuserv on an X XEmacs. 2. Start gnus. Quit it. 3. Start a tty gnuclient. 4 Start gnus and enter any group. The SPC key which runs `gnus-summary-next-page' does not work, i.e. it does not scroll the article as is supposed to. This problem does not exist in 21.1.12. I cannot test it on 21.1.13, 21.1.14 as tty gnuclients on these versions crash too often for me. (I've submitted a bug report.) I don't know how to debug this and the folks on the ding list suggested that I post this here. -- Nevin
