The Logi+ app works a lot of the time but i frequently find that it locks up and requires a windows restart - potentially because I do not have admin access to my work laptop or one of the nanny applications from my security team does something? not sure... but anyways, i suggest writing the configuration to the keyboard/mouse and not depending on the logi+ app or services to be running for normal usage. in my case, i don't use application specific settings, the app doesn't sync my settings across multiple computers and i don't change my profile a lot.. so... why not just do without the app for normal use?
