This is for CS4.
I can group two objects A and B (say two drawings) and then insert (copy & paste) the grouped object into a text frame as an inline frame. However, if object A is already in the text frame as an inline frame or anchored object, I cannot group it with object B.
Similarly, if I have an inline object which is a group object, I cannot ungroup it unless I take it out of the text frame (in which case it is no longer an inline frame or anchored).
Is there a way to group an object A with an inline frame or anchored object B, without releasing object B from its anchored status first?
