Word 2007 is quite different than previous versions. One of the more aggravating features is it's addition of extra space between every line of text by default. The easiest and quickest way to fix this problem, is to click on the "line spacing" button to change the "Remove space before paragraph" option. This will stop Word from messing up your document, should you NOT want to double-space everything. I agree that the default of most in the academic community is double-spaced, but I thought Word 2007 and the entire Office System is aimed at business, not academia. In the business world the main method of operation for documents is single-spaced. Go figure. You can still download the Word 2007 beta, as part of The 2007 Office system from Microsoft. A Windows Live (formerly called ".NET passport") account is required.
