10 years ago Negative, theres two UI_INITIALIZEs. One in the usual spot and another after the delay. Agreed its a botch to address the symptom not the real issue.
Also, closing this as in latest version default seems to work OK now
Modified setup() to work with our I2C LCDs a bit better, also provides a bit more detail logging during startup to help troubleshoot where it gets stuck
