As a longtime user of the MX Master 3 mouse (connected using the USB Unifying Receiver) and Logi Options software on Windows 10, I have been very pleased with the productivity the combo provides. I have set up many specific apps with programed keys. The Global Setting includes programming the Middle button as “Start” to open the Start Menu. It is important to note that this setting worked without ever changing the scroll wheel mode.

I tried the beta software for Logi Options+ with my MX Master 3 and all the same settings with the exception “Start” which is now “Keystroke = Windows Key.” I began to have intermittent issues with the scroll wheel switching from Free Spin to Ratchet when I pressed the middle button to open Start. I reported this issue using the Feedback hub in the app multiple times. I was forced to go back to using Logi Options to remedy this issue. As each new version of the beta for Logi Options+ was released, I would try it with the same result and again return to Logi Options. When the release version 1.0.5155.0 became available, I once again installed Logi Options+ and found it produced the same issue.

With the much-appreciated discount coupon for testing the beta software for Logi Options+, I purchased the new MX Master 3S (connected using the USB Logi Bolt Receiver) and installed the Logi Options+ software (ver. 1.0.5155.0). It was working fine and then the issue with the scroll wheel randomly switching from Free Spin to Ratchet started happening again, so I took to the Community Forums in search of answers.

I finally found someone who suggested the issue could be related to the “Power Saving mode” of the mouse. After testing this theory, I discovered that if the mouse had been idle for a while, it went into Power Saving mode. Evidently this causes the mouse to lose connection with Logi Options+ software which also means all the settings for the buttons on the mouse use the hard-coded defaults. The default for the “Middle Button” is “Shift Wheel Mode” and so after being away from the computer for a while and returning, pushing the middle button to open the Start Menu without first moving the mouse caused the wheel mode to shift from “Free Spin” to “Ratchet.” If the mouse is moved first and allowed to come out of Power Saving mode everything works as intended.

Although I have a work-around for this issue for now. It would be great if someone could please explain what exactly is going on. As I said, the issue first occurred when installing the Logi Options+ software with my MX Master 3 mouse. Nothing about my computer system was changed except the Logi Options+ installation. This would lead me to believe that there is something coded differently in the software.

Thank you for your attention to this matter.
