Hi Not sure if this is a known bug but couldn't see any reference to it. Specific case is Reflection switch, firmware 1.4.0. Trying to set key function as: [INDENT]Short Press - Idle Short Release - Idle Long Press - Toggle Long Release - Idle[/INDENT] After saving and re-opening, Toolkit shows all as Idle. Toolkit also programs physical device as all Idle. Experimenting in the office with a variety of key inputs showed a problem with: [LIST] [*]Ramp Off [*]Toggle [*]On Key [*]Off Key [/LIST] Any of those in the Long Press would cause toolkit to save key function as Unused. Cheers Matt
