I've submitted this as a bug report but I figured I'd post here too.
This is probably quite minor, but basically when you drop a script into an object using CTRL-drag, it does not trigger the changed() event in any scripts there.
It seems that the potential for exploiting this is minimal, as CTRL-dragged scripts appear to always become inactive. However it is kind of annoying that my scripts do not then know of this extra item. What if an item is expecting a script do be dropped into it and to make it available for sale or such like? Wouldn't see it until an item of a different type is dropped in.
So as I say, fairly simple, but kinda annoying at the same time so it would be neat if it were fixed =)
