Hello, On a K740 wireless keyboard, when I deactivate the feature "F1,F2 etc. keys as std function keys", and the I press the "-" key in numerical pad, instead of typing the "-" symbol, the MS windows user session gets locked (as when user would press "Windows" key + "L" key to get computer locked). It is a bug. Never happened anything like that with old "Logitech Options" predecessor tool
