When I hit Filter → Shape Order, it took me to a full screen window of Shape order. When I exited the full screen, the shape order window became so.
I couldn’t close the tiny window since it was so infinitesimally small. So I hit Filter → Shape Order again, and this error popped up: “-[NSMenuItem setController:]: unrecognised selector sent to instance 0x600001163f00”. (I can’t add more media images since I’m a new user.)
Now this window wouldn’t go away no matter what I did. So I tried to quit the app, but that was also not an option.
Finally I had to force quit the application by pressing Option+Command+Escape.
