I recently did a group paper in Word, but when one of my Japanese friends
emailed me her part of the paper, it changed the preferences on my computer.
I now have Asian Typography settings (which I don't need). But the real
problem is when I open a new document, I have these grey lines (one vertical,
one horizontal) that intersect at each of the 4 corners of the page. Looks
like an L on the upper right hand corner, reverse L on the upper left, etc.

I have searched high and low for a setting to undo this, but can't seem to
find it.

How do I remove it? And if possible, can I uninstall the Asian Typography
features that I have no need for?

THANKS.
