I've done this lots, grab the control module, or command capsule, and the whole multi-stage rocket assembly moves up or down on the mouse wheel. I now have an assembly that I can not move up or down, no matter where I grab. ---------------- DOH!!! -------------- The solution: Save a copy of your design. Open the .craft file you saved with a text editor, to find the FIRST part you put down. That is the one you have to grab, to move the whole assembly. Hopefully, you can still see it in there, behind all the boosters :-)
