FluxEngine windows gui controlling greaseweazle hardware handles case where greaseweazle on, but drives turned off after starting fluxengine, badly #806
Description
setup: I am using a greaseweazle v4.1 powered by usb power (jumper set) while powering the drives externally. I am using the fluxengine gui from windows, Apr 19, 2021 dev build, commit checksum 9ce405c.
issue: fluxengine client becomes frozen, and cannot be closed, stopped, etc.
steps to reproduce: have fluxengine connected via usb power via shorting the 'usb 5v enable' jumper, plug it in. turn on power supply powering drives. start fluxengine gui. turn off power supply powering drives. greaseweazle is still plugged into usb, and thus still powered. attempt to write disk with fluxengine gui.
fluxengine will now be frozen. in this state, without resorting to task manager, unplugging the greaseweazle will cause the client to close. I have found no other way to unfreeze the client in this state, including pressing the 'stop' button, or attempting to close the window via normal means, suggesting that it stops responding to window stop signals.
