[Xastir] What is very large rectangle with X in center on station?

[David A Aitcheson]

Curt,

I also saw Tom's response first. I looked in my spam folder on Gmail;
the original and another Xastir related message from Bill had been
flagged as spam.

I have noticed this as a trend ever since Microsoft bought up Github...
makes me wonder.
