CC2018 Marquee Selection - how to simply select objects and not move them
Hi all, I'm a newbie to Illustrator and having troubles learning the marquee selection tool. I am following some instructions in the Ai Classroom in a Book which seem to suggest that I can highlight objects by dragging over them using the selection tool. What is happening though is that as soon as I click and drag over the objects I wish to select, the entire group of objects is moving. I don't want to move the whole thing, I simply want to highlight certain objects within the group. Is this possible? I imagine I am doing something wrong, but I've followed the instructions to the letter and can't seem to make it work.
Thank you
