I'm finally on a level I'm stumped on, and, from what I've read on the forums, others are stumped on this level too -- 3.8. I can't figure out how to get that crate placed where I can climb up the one ledge. It seems that you would -- when starting the level -- need to go up the elevator, push the one crate over the red button to cause the slot to open; then go down the elevator, and push the other crate over to allow you to climb up that ledge, but I can't get it placed where I need it. Just a itsy-bitsy hint without spoiling anything else. EDIT: Sorry about the multiple posts. Kept getting an error msg. when I posted, saying to try again in a few minutes. Didn't realize each one got posted.
