I must have accidentally clicked some magical combination of keys to get this, but for some reason, I open one document and two pop up with the same name, but a :1 and :2 behind them. Any ideas what the heck I may have done? I haven't seen this before in 15 years of using Illustrator!
Is it supposed to save the "I don't want two windows" option? It keeps opening two windows for me when I shut down Illustrator and open up that one file again. It's kinda funky, but I am glad to have learned something new today. 😉
