wrong frame position with --fullscreen

wrong frame position with --fullscreen

[Stephan Hennig]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Steps to reproduce:
* Put desktop task panel at top of screen.
* Start emacs with 'emacs -Q --fullscreen'.

Symptoms:
* Emacs' frame appears under the task panel, i.e., Emacs' title bar
  and part of menu bar are hidden behind the task panel.

Expected behaviour:
* Emacs obeys task panel position when positioning the frame.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
xxx/emacs/etc/DEBUG for instructions.

It is a known bug/misfeature. Currently, Emacs' fullscreen support in
Windows is not very good. It doesn't grok multiple monitors, for
example. As a workaround you can move the frame to the right place,
either from your .emacs, or with registry settings. Also, I have a
(not very well tested) patch somewhere that fixes this problem
("tiptoes around" would be perhaps a more fitting description). Yell
if you want to give it a try.

I have for long time had a fix for this in the patched version of 
Emacs+EmacsW32 too. This patch is incomplete, since the bottom part of 
Emacs window, below the minibuffer (or at the bottom part of it) is 
sometimes not redrawn.

I would be glad to incorporate your patch there for testing. There has 
been no complaints about the current patch, except for the redrawing 
which is a little beauty problem in only some special cases. However 
that does not mean that I know that it is otherwise correct. Kim said 
once that he was unsure whether there are problems with maximized 
windows and the current display code.

Thank you for looking into this.

Thanks.  I haven't set up a build environment for Emacs yet.  So I won't
yell today or tomorrow.  (As a start I've just compiled the AUCTeX
package for the first time.)
