If you need a distraction free writing environment, grab a copy of Dark Room. I found it after a few years of using WriteRoom, the original, on a Mac.
I write most of my draft documents in it. Then I move them to Word and apply formatting. I write all blog entries - exclusively in Dark Room - every post.
It does what every text editor should be doing first. It makes you concentrate on the subject.
And, best of all - it's small footprint, single .exe app. Xcopy it to your path. Bam.
