mouse pointer moves unexpectedly

mouse pointer moves unexpectedly

[Peter Münster]

Hello,

When
- switching from summary buffer to article buffer (h),
- then removing splits (C-x 1),
- then pressing "n" (gnus-summary-next-unread-article),
my mouse pointer moves near the upper right corner of my emacs X-window.

How can I tell Gnus, not to move my mouse pointer?

TIA for any help!
Cheers, Peter

(already posted at gnu.emacs.gnus, but people told me, that it would be
better to try it here)

I don't think Gnus moves the mouse pointer.  Are you sure you haven't
enabled `mouse-avoidance-mode'?

Yes, I'm sure. You can reproduce this behaviour even with "emacs -Q".

I can't reproduce it at all.

Strange...
Adam Sjøgren and Robert Marshall, both using Emacs/24.0.50, can
reproduce it.
( http://groups.google.com/group/gnu.emacs.gnus/msg/7fdc86fd6510c3de and
http://groups.google.com/group/gnu.emacs.gnus/msg/aa9dad84eb42a062 )

What could be the difference?

The people who can reproduce the bug has to debug it.  :-)

I would like to do that. My idea is to start from a backtrace, then
analysing the functions that are called when pressing "n".

But I need some help: how can I get such a backtrace? debug-on-error
does not work, since there is no error (just mouse-movement...).

TIA for any help,

`M-x edebug-defun' on the function you want to debug usually is the
right way to step through the actions.

However, I think the only way the mouse pointer can be moved is with the
`set-mouse-' functions, and grepping shows that Gnus never calls those
functions.

Giving up. Before debugging, I should learn lisp...

This is the trace, too cryptic for a beginner like me:

--8<---------------cut here---------------start------------->8---
Debugger entered: nil
  edebug-display()
  edebug-debugger(0 before nil)
  edebug-before(0)
  (edebug-after (edebug-before 0) 17 (gnus-summary-next-article (edebug-after ... 11 ...) (edebug-after ... 16 ...)))
  (lambda nil (edebug-after (edebug-before 0) 17 (gnus-summary-next-article ... ...)))()
  edebug-enter(gnus-summary-next-unread-article nil (lambda nil (edebug-after (edebug-before 0) 17 (gnus-summary-next-article ... ...))))
  edebug-enter(gnus-summary-next-unread-article nil (lambda nil (edebug-after (edebug-before 0) 17 (gnus-summary-next-article ... ...))))
  gnus-summary-next-unread-article()
  call-interactively(gnus-summary-next-unread-article)
  byte-code("^H!\210\207" [func call-interactively t] 2)
  gnus-article-read-summary-keys(nil)
  call-interactively(gnus-article-read-summary-keys nil nil)
--8<---------------cut here---------------end--------------->8---


I've found a workaround:

(defun my-alter-article-map ()
  (local-set-key "1" 'delete-other-windows)
  (local-set-key "n" "hnh1")
  (local-set-key "N" "hNh1")
; and so on
)

I don't see those messages in gnu.emacs.gnus on news.gnus.org, oddly
enough...

Never mind.  I wasn't looking hard enough.
