Using Excel in Split Screen

Update: Excel 2013 and subsequent versions allows for split screen without using the below method. This is applicable to Office 2010.

Update 2: To use Excel 2003 in Split Screen; after you have the first file open by whatever method, hold Shift down and click on the Excel Icon on the Taskbar to open the second copy. Then use File -> Open to open the second file.

Want to use Excel like this;

Instead of like this;

Simply open a new Excel window from the Start menu, then open the required sheet from within the window (File -> Open). Just repeat for the desired number of windows you want open. 

If you use Excel as much as I do on a daily basis, this is a big time saver.
