We implemented a new feature in dual monitor handling:
the windows that are actually in the second monitor are
listed at the end of the list and their background is gray.

As neither Chris nor I have actually a second monitor to
perform the required tests, we kindly ask for help testing this functionality
to work properly before issue the new version.

You can pick the latest development version from mercurial version control
with the command:
hg clone https://giuspen-x-tile.googlecode.com/hg/ x-tile-dev

Cheers,
Giuseppe.
