Ah yes, I think that's what happens. (Or, it's flashing when it's
loading the first splashscreen thing - which is much larger. Maybe it
currently does flash but only once, really quickly, so you don't see it
or something... my E2 is out of the case so I don't have LEDs wired
up.)

Good stuff! I forgot to upload the other night, but there's a new
version of the monitor that you may find more useful:
http://www.axio.ms/projects/e2/e2-monitor-0.24-README
..contained in..
http://www.axio.ms/projects/e2/e2-monitor-0.24.tgz
This version boots other stuff from flash (so is actually useful (he
says - my biggest test program so far splats a big image on the
screen...)). The XMODEM stuff should be slightly more
resilient/well-behaved but still isn't perfect.
Cheers,
Matt
