Alright, I use to be able to open two documents and they would open up into
two separate windows so that I could compare them side by side. Now, when I
do that, both sheets open into the same window.

I can open one, and then open excel and open the other document in excel to
get it to work, but often it will freeze excel.

Are there some settings that need to be reconfigured to open both sheets
from the file location?
