We use dual monitors at work (vertically) and stretch the Excel window onto
both monitors. I didn't notice this until Excel 2007, but we are having a
strange issue:

When the screen saver comes on then gets deactivated (moving mouse, etc),
Excel goes from being on both monitors to being only in the top monitor.
Then we need to re-stretch the Excel window back down to fill the second
monitor. This happens every time the screen saver goes on and back off. The
real problem is that some of the guys at work don't know how to fix it and
they mess things up trying to do so (maximizing the Excel window rather than
re-stretching, etc). We also cannot disable the screen saver because the
ability to change the screen saver settings has been locked out by "the man".
:)

Why would the screen saver do this? Can it be prevented? This happens even
if Excel is the only window open on the desktop. This doesn't seem like it
should be an Excel issue, but I never noticed this until we upgraded to
Office 2007 and trust me.... I would have noticed this because it is annoying!
