I can't change anything inside the Cura 2.1.2 window by clicking on it, and I'm stuck at the "Add Printer" screen. I can't even x out of it, I can only shift focus to the window (two, really, one for cura, one for add printer) by clicking there. The mouse pointer does change to an I shape when it's over the "Printer name" text box, but I can't click inside to edit it. Has anyone heard of anything like this? I've tried searching, and I can't find anything.
