If you go to Options in Tools in the toolbar, and click onto the "General"
tab, you'll see a small checkbox "Allow starting in Read Layout"--uncheck
this and you're go to go. I find the Read Layout a pain. But as for opening
it to Normal Layout... apparently once you've opened the document and change
the view, then save it, Word will retain this layout out...
However, per Microsoft's note on defaulting your own preference:
"Note: You can't set a default for all documents that you view in Word,
because the view setting is stored with each individual document as a
document property. You can save your document in the view with which you want
it to open. Documents that you receive from others will open with the view in
which they were previously saved."
