================================================================
Dear Bug Team!
xemacs is slow on aix. Selecting things with the mouse is sluggish and
xemacs permanently uses
more than 30% cpu. I am running it under gdb, when i interrupt via
control-C, bt shows me the following:
^C
Program received signal SIGINT, Interrupt.

I have also attached the output of truss.
I am running the latest mercurial version. (hg up did not show me any
changed files as of today)
Since I would like to use xemacs for serious work, I'd appreciate hints
for a quick fix.

thomas

-----------------------------------
Auto save file for draft message exists; consider M-x mail-recover
Warning:
Defaulting to the GNU Emacs-derived `sendmail.el' mail client. This
facility,
while part of base XEmacs, is heinously underfeatured, and not going to get
better in the medium term. We include it so that bug reports work without
packages; we suggest that you choose and/or install one of the other mail
clients from packages if you're doing something other than M-x
report-xemacs-bug , or even if you are reporting bugs regularly.
To choose a package from those installed, click on "Options" ->
"Internet" -> "Compose Mail With ..." and decide on one from the
list. Gnus and VM are full-featured and have active user communities.
To disable this warning and stick with the old behavior, you can explicitly
initialize `mail-user-agent' to 'sendmail-user-agent .
