Hey!

I have used the MX Master series mice for god knows how many years now. Among all the things it does perfectly there is one issue I keep running into. Let me describe it to you:

I use the thumb buttons named "forward button" and "back button" for two different things.
System wide they function as forward and back.
Within AutoCAD they function as Undo and Redo.

I switch applications and virtual desktops a LOT and do so quickly. Upon doing so the Logi+ software often loses track of what application is currently active and the functions assigned to the mouse buttons stop working.
I have to physically turn the moue off and on again to regain the functionality.

This issue has persisted for years and happpens several times a day.

I hope this helps you, the developer(s) of the code behind this nifty device!
