OK, it happened again, and this time I took some pictures (worth 1000
words, right?).

Again, it was cold outside when I powered up (28F or so)- not sure if
that has anything to do with it...  Soft reset fixed the problem after
I took these pictures (I've stacked three screens - the last one is
paused in "small spectrum and elapsed time" mode).

Any clues?  Is this a defective unit, or does it just not like to be
cold?  Could there be a loose solder joint that gets triggered in the
cold?

Thanks for any insight!

temperature range for commercial components is 0-70C (32-158F), so you might easily be just out of proper operating temperature unless special effort was taken to build with industrial components. I'd be surprised if the display was made for outdoor exposure. Self-heating seems to be enough to get in back into range if a power cycle fixes it after a few minutes. Hard to say what kind of damage may be going on. It's possible that it isn't hurting things, but you never know. I'd be worried about condensation.
