Adobe illustrator CS4 freezes in OS 10.11.6 El Capitan?
I am using OS 10.11.6 El Capitan and when I start up a file in Illustrator CS4 the file shows, but the whole Illustrator application is frozen. Can't even move the window. So I have to quit the application. This only happened when I upgraded from the previous OS. I trashed the Illustrator preference (.plist). That made no difference. I trashed the Adobe font cache. That made no difference. Has anyone else had this happen? And if so, is there a work around?
MacBook Pro, iOS 10, OS 10.11.6 El Capitan
