Blink1Control Mac crash in net code (due to sleep?) #216

Closed todbot closed 9 years ago

todbot commented 9 years ago

Blink1Control has been reported to crash on Mac OSX perhaps when the computer is going into / coming out of a sleep cycle.

Top part of crash report from user with thread that crashed is below. Looks like it might be due to a Qt network request behaving badly when the network is unavailable, like what could happen when a computer is coming out of sleep and needs to rejoin WiFi.
