can't see bottom of new widget to accept changes and set up

Me again....I seem to recall encountering this in the past and I can't remember what the workaround was. I just created a new dashboard and widget. I'm working on my laptop and I can't seem to get to the bottom of the screen where the button to accept the input into the widget is and set it up. I've tried using Pg Down, arrow keys, minimizing, stretching. Nothing. Any ideas?

Thanks, again!
