return key buggy?

I’ve been experiencing an annoying bug the past few weeks. When I try to unlock a file and the “unlock file” popup appears, I used to be able to hit “return” on my keyboard to unlock the file. Now, “return” dismisses the popup, but it doesn’t actually unlock the file. I have to mouse-click the button to actually unlock. It’s happening in Chrome and Safari. It’s more annoying than mission critical, but I’m curious whether anyone else is experiencing this!
