if that happens again find a "Deruth-er" post.
you can get it free from people and if you can rez on the land rez it, sit on it, then it should clear up.
Not a perfect thing but go to a Class 4 or 5 that you know is that a 4 or 5
now TP to the other region going from a C4 to a C5 or vice versa puts a message up that the simulator is running a different class than the one you were in.
edit one item, hold shift, click the second item, finally you let go of shift and hit "Link"/Ctrl-L
this is assuming that you been edit one item, hold Ctrl-L then try hitting the second item.
Try using shift instead of Ctrl when selecting multiple objects...that give you only 3 arrows to fiddle around
and Tools Menu works well enough to get it linked without needing to hold Ctrl
