When doing a File Open, Build 638 creates a new window to open the document in.
I don't think this should always happen.

For example, if I start the word processor with no document (i.e. unedited and
untitled), and then do File Open to open an existing word processor document,
the file I opened will appear in a new window, and you are left with an extra
window with nothing in it.

What shopuld happen, IMO, is that either the file is loaded into the current
window (i.e. Insert File) or the old window closes.

Now, if I am in word processor and I File Open a spreadsheet for example, this
SHOULD open in a separate window.

Or, if I am in word processor and I have typed something (i.e. perhaps untitled
but edited), then File Open on another word processor file should open a new
word processor window.
