Illustrator n'ouvre pas la fenêtre du document mais le considère néanmoins comme ouvert, il faut redémarrer Illustrator pour que la fenêtre puisse apparaitre.
Yeah, i've found a better workaround for the 'ghosted window' , just open a 'new window' , the ghosted one stay there but I can work on my file without restarting illustrator !
Here is a screen capture of the window panel with the "ghost file" opened
Hello, it happen only with the last version (26.0.1) and as i can see, it appens more frequently with an other window opened ( i use tabs to see all my works ).
I can work on other files but the "new window" still hidden.
This bugs occured randomly and is not easy to reproduce.
Does it happen in this version only, or did you have this bug in previous versions too?
