Preview not working
Preview Application on my MacBook Air not working. The application keeps opening up a pdf that i had opened via an email attachment. Thereafter there are 2 or 3 blank windows behind the Preview window. I have to force exit every time. Nothing else works on the application. Ive tried restarting and shutting down. But the same thing keeps happening no matter what I try opening. PLEASE HELP!
Running mojave 10.14.6
