Help Please. I am running illustrator CS4 on a Mac.
While working on Illustrator files, drawing, saving and opening/closing files over a perior of time, I suddenly get this message "Cannot finish previewing could not complete the requested operation."
When this happens, the screen goes into Outline Mode, sometimes it allows me to save, other times it crashes CS4 Illustrator.
This is resolved by restarting the computer and relaunching illustrator. I have not had any problem at the launch of the application.
Please help! This is now happening multiple times per day.
