This is in violation of the ILDA spec. It's not Pangolin's fault. (Note that the same thing will happen if you yank the USB cable out of an Easylase USB controller.)
Just a small correction (Sorry but I haven't read this earlier):
If you yank the USB cable out of an Easylase USB controller, the actual frame will be repeated endless.
If your SOFTWARE outputs a static beam, yes, this beam will be output endless.
(EasyLase 1 will not ask what pattern you output).
If you yank the USB cable out of the new EasyLase II, outputs will shut down.
After reconnect, output will continue.
Naturally, every hardware or software may lock up due to different reasons.
But this is not the normal operating condition.
