I've been having similar problems using illustrator on Mac OSX too.
Often only copies the text.
Sometimes it will copy objects but the CMYK values are different (even when the doc profiles match).
The only (temporary) solution is hitting command+c several times before pasting (at least three).
Not helpful when five of the last fifty documents are a different colour to the rest of the clients files because old habit takes over and I forget to copy multiple times.
Surely there has to be a fix. Right?
