At seemingly random occurrence, these days a few times per day, finder seems to confuse files.
When opening a file from the column view list, or when dragging the file into another application (as an attachment for example), the wrong file is opened or sent. Usually it is the next or previous file in the list of files that I'm looking at.
When the wrong file is opened I can notice it immediately, but when sending the wrong file there is no way of telling, even in the email the filename I intended will show, but the recipient will receive another file.
It has been happening on two computers, one running el capitan (10.11.6), the other running sierra.
I'm not sure if this is related, but I always use the Column view in finder, I still have to test if it happens in other views as well.
Does anyone have a clue why this is happening?
