Have you ever gone to click on a note in the list only to have the mouse still moving a millisecond after the button comes up? You then get the warning about sorting notes in a custom fashion and have to cancel that before you can do anything else.
For me, clicking on a note is something I do frequently and I must make a conscious effort to make sure the mouse has completely stopped moving before I release the mouse button. I wish I could turn off that warning.
This is on a Windows 10 system. I don't use tablets or phones for entering notes, just for reading them. If the mouse is moving at all, that message comes up. I likely see it a few dozen times on a busy day.
