[Motmot] Various announcements, including FView updates

[John Bender]

Thanks, Andrew. 64-bit Hardy, Basler A602f-2 camera. And still no
information gets printed out. Does this sound like the problem I
half-fixed before, where I had to make it wait until the 10th frame
was received from the camera before I started to run any of the
drawing or callbacks? Just a thought; I'm not sure what you've changed
recently.

PS: I can give you an account on this computer if you want; I
guarantee you can replicate it that way.
