change in Emacs highlighting behavior

change in Emacs highlighting behavior

[mafaeq]

Hi all,

I recently upgraded from Ubuntu 9.04 to 9.10 and since the upgrade, emacs
has been
behaving differently. Specifically, when I left-click on the scroll
scrollbar, it sets a mark 
whenever the cursor moves, causing the region betw where the cursor was and
where it
is to become highlighted. This also happens if I left-click and drag along
the scrollbar.

It didn't behave like this before and I find it very annoying!
I've tried turning transient-mark mode on/off but that doesn't make a
difference.

This is the version of emacs that I am using:

GNU Emacs 23.1.50.1 (i486-pc-linux-gnu, GTK+ Version 2.18.0)
of 2009-09-27 on palmer, modified by Debian

I've tried removing and re-installing emacs and I've deleted my .emacs file
and .emacs.d directory,
just to make sure there was nothing there causing this.

Oh also, when I start emacs I get the following message in the terminal

(emacs:3741): GLib-WARNING **: g_set_prgname() called multiple times

I don't know if that is related, but it's also new since the upgrade to 9.10

Any help would be greatly appreciated!

Sorry, can't help you here (I don't use scrollbars or the mouse), but ...

This is not a released version of Emacs.  It is almost certainly a
"pretest", i.e. a beta test version, released by the Emacs development
team to those willing to test it.  A released version would have a number
like "23.1.1", where "23" is the major version, "1" the minor version,
and  "1" meaning it's the first time it's been compiled.

You can start with "emacs -Q", which avoids loading your .emacs etc., to
check that it's Emacs at fault and not your own files.

If you are a public spirited person, you should send a bug report to
Ubuntu or even Debian.  Though, best of luck finding a person willing to
accept blame.

Otherwise, I'd recommend you to download the latest stable, released
version from this address:

    http://ftp.gnu.org/gnu/emacs/emacs-23.1.tar.bz2

(or one of the other files in the same directory (there are MS-Windows
versions there too)), and unpack, build and install it.  That version
would work properly.  With a modern DSL line and a modern PC, this whole
process would take less than an hour

Both of these should be fixed in a more recent snapshot than the one you
are using.

Thank you both!  the suggestion to set GDK_NATIVE_WINDOWS=1,
(as posted in the debbugs forum) before starting Emacs resolves the 
highlighting issue.
