I'm probably going to need a little more info to help you out. By "free shape" do you mean scaling tokens or and/maps? As for not being able to move the tokens or maps, double check that you are:
(A) On the right layer to interact with the desired elements - Cycle through the GM Info Overlay, Objects & Tokens, & Map & Background layers to see if you were on the wrong layer to interact with them.
(B) Double check that you are viewing the board as a GM and not as a Player. At the very bottom of the "My Settings" tab there's a button that either says "Re-Join As Player" or "Re-Join as GM". If you are seeing the second, you're technically viewing Roll20 as a Player and only have the limited permissions a player has. (A player can only move objects and tokens on the token layer and only those that they have assigned permission to move.)
