Fields blew North

[Ken Norris]

OK, here's a mystery:

I have an Anchor window, a palette window and two nearly identical standard
windows.

For no reason I can imagine a field (the 'same' field) in each of the two
standard windows disappeared. I didn't know if they got deleted or
what...haven't run across this behavior before. I found them in the
Application Browser and got the Inspector to show the settings.


Oddly, both of them had gotten blown out the top of their respective
windows. Both showed a loc of -83, way above the Arctic Circle. Fortunately,
I was able to use the Browser to 4WD them separately down through the tundra
and back into their windows.

Everything is back to normal...._but_, I need to know what the heck
happened.

Any clues?

TIA,
Ken N.
