Right Click gray box -> Display Performance -> High Quality Display
Both doesn't work..
I;m not sure if this is why but, as soon as the program starts, the program asked me if indesign could access my files, I accidentally clicked N0. Could this be reason? If so how can I change the setting?
It is posilbe that the preferences for display performance have been changed. Below you can see my preferences for Typical Display. Perhaps the Raster Images preferene has changed for one of your display options.
