I tried what Jorge suggested and now I get a whole lot of errors. I changed the setting back to what it was but still the errors appear.
Code:
Traceback (most recent call last):
File "./gmoccapy_handler.py", line 2300, in _on_fo_counts_changed
difference = (counts - self.fo_counts) * self.scale_feed_overide
AttributeError: HandlerClass instance has no attribute 'scale_feed_overide'
There are two more that are similar - all to do with scale_xxx_overide
EDIT: In the debug trace I found this. Don't know if it will help any.
Code:
**** GSCREEN INFO: Preference file path: ~/.gmoccapy_preferences
