Anyone else having this issue and know a fix for it? When I opened the file, all is well. Then when I zoomed in (either with mouse, magnify glass or the keyboard), it filled in all white spots with black. I've had this happen with a few other files.
I've uninstalled Illustrator and reinstalled (without saving preferences). I tried closing the file and reopening. I also tried quitting Illustrator and reopening. Still having the same issue. Thanks for the help!
