Unfortunately, that’s not it. The black box is what opens when I double click. Sometimes they will open and sometimes I will just a few seconds later I will get the black box. I can’t figure it out. It’s like a bug in my software, I think.
Excellent! That worked. I didn’t initially think that was the issue because I was trying to create a new layer, so I didn’t think the properties of the other layers would matter. But that indeed fixed it. Thanks a bunch for your help!
