your options+ software has gotten to be probably the worst software i have ever used for anything on my computer as it crashes atkleast 10 times a day and everytime it crashes then i lose funcationality on the majority of my mice buttons including the scroll wheel as well as my customized buttons on my mx keys. Such a terrible program, and I have contacted support numerous times and all they can say is UHHHHHH maybe a version soon will fix your issue. I will never buy another logitech product as im actively searching for better mice and keyboards out there
