Yes, I get that with Word 2000 on NT4, but the problem appears to be in
Word's preview, and definitely the lines are in the file.

1) The Word document prints with all the lines, and looks correct.
2) If you preview in Word and magnify, you can see all the lines.

Interestingly

3) If I copy to the clipboard as a metafile and paste into Word, I
do see the lines, but if I copy the graphics device to a file I do not.

Also

4) I have seen this with metafiles from S-PLUS 4.5 to Word 97, and 3) also
held true there

I suspect that the anti-aliasing built into the NT4 display engine is
losing narrow lines completely (it does a poor job of small fonts), and if
you do what you did, you will get a much larger nominal page and hence
relatively narrower lines than copying a graphics device to the clipboard.

I might try setting width and height on the win.metafile device to
something much closer to the size you want to include at. (I haven't
do so, though.)
