Actually, it seems to keep turning BT on now. Which is odd, because it's only when the DCEW is placed on the desktop, yet without pushing on it. Like it's running the script without being called?

Edit: unchecked "Update when switched to the desktop", now it behaves normally (turns BT on only when called).

Edit: does not connect to defined MAC address after being called. Buuuuuuuut it helps when I put the right MAC in. D'oh!
