21.2.25: tab not updated on C-x C-w

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 21.2 (beta25) "Hephaestus" [Lucid] (i586-pc-win32) of Tue Dec 28 1999 on DELTA configured using `configure UNKNOWN' Please describe exactly what actions triggered the bug and the precise symptoms of the bug: Don't know if this is fixed in later betas, but...I just noticed that doing `C-x C-w' to write the current buffer to a different filename doesn't change the tab (but does change the modeline). For example, I do C-x C-f foo RET and the tab and the modeline both identify the buffer as "foo". Then, I do C-x C-w bar RET and the tab still says "foo" with the modeline saying "bar".
