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
