It's not an idea other than Logi Options messes with my mouse and interferes with selecting items, Shift-Click etc - multiple systems, all Logitech devices.

After opening app it appears to clear the issues!

Also - since I'm here... (I have MANY Logitech devices) I do not like the default settings for our K400 KBs (also - multiple) - Default (without software should be STANDARD keys - not Fn Locked.
