When I sample a colour from a masked object in Illustrator CS4 it doesn't sample the colour correctly. It looks like it's doing it optically rather than using the exact colour breakdown I have assigned the colour. It doesn't even look like the same colour when I colour another object. It will often be slightly darker. Does anyone know if this is a bug or if there is some other reason it is happening. Never happened in any of the other versions.
It’s a long known bug that Adobe is probably not interested in ever fixing.
Yupp, as Scott said. Ugly annoyance.
