Update just came through. Still does not manage to switch mouse settings between 2 applications like it used to.

I have - one - mouse setting and have to change it if I want to open say AutoCAD, then change my mouse settings again back to 'general use'.

The old version, the green looking app worked better. Broke a working wheel, vs don't fix if it ain't broke.

I feel this is Logitech planned obsolescence. Which will result in me not buying the new Mx Master but hurting your brand for the duration of my life and my children's life, eventually I will switch to your direct competitors.
