Footnotes + undo

In XEmacs 21.1 (patch 3) "Acadia" [Lucid] (sparc-sun-solaris2.6) of Tue Aug 3 1999 on fsui02 configured using `configure sparc-sun-solaris2.6 --prefix=/usr/local --bindir=/usr/local/bin/sparc-sun-solaris2.6 --site-prefixes=/usr/scratch/sect4/cgw/local' Please describe exactly what actions triggered the bug and the precise symptoms of the bug: C-c ! a -- footnote #1 is inserted C-x u -- any mention of footnotes in the text disappears C-c ! a -- footnote #2 is inserted (while footnote #1 is expected). Undo should probably probably decrement footnote counter in this case. Gleb
