Porthos,
I've got a Glo too (no HD too) but mine is always with fw 3.19.5761 and not 4.2.8432 like you... have you tried this link too fix your problem with nightmode :

It's seems to be the solution
BUT on a 4.2.8283... I don't know if it runs on a 4.2.8432.
I'd like to have the opinion of KevinShort on it, and perhaps (not perhaps, I'm sure !) he will give us a version v14 of his famous nightmode plugin that will be compatible the last firmware
