I'm becoming frustrated with the Options Software not working as it should. I have mapped the side buttons of my Anywhere 2S mouse to perform the "windows +" and "Windows -" shortcuts and it fails many, many times. I have to open the Options software to make it work. It should work always, without the need to open the application. I upgraded to options plus recently and it seems that the failures are more often. The same happens qith the "lock" key of my MX Keys, it is remapped to put the computer to sleep but it fails and just performs the default setting that is lock session
