Excel 2003.

How do you go about opening a separate workbook in its own window? Similar
to how MS Word opens a new window for each document. I have 2 monitors set up
(laptop with desktop monitor attached) and I work with too many spreadsheets
which I would rather be able to view on separate screens rather than having
to switch from one workbook to the next. Simply arranging the windows (eg
tiled, horizontal, vertical) reduces the viewing area too much.

Any suggestions?

In addition, when you close a Word document via red box 'x' - top right, it
doesn't close all other Word documents that are open. Is it possble to do
this in Excel?

Thanks.
