Can't change the layer of an image

[graham samuel]

I've got a card with a lot of little images on it. Just one of these  
images disappeared (I couldn't see it on the card) so I concluded it  
was probably covered up. I was able to select it with the Property  
Inspector, but I couldn't reset its layer number, either by typing a  
layer number directly or by using the various arrow buttons for that  
purpose in the Inspector. Its layer position was unremarkable (layer  
68 when there are over 100 objects on the card). The image was not  
locked. I finally got it back by cutting it and then pasting it back  
onto the card, where of course it appeared in the topmost layer.

Can anyone suggest what caused this problem - was it something I did,  
or is it an obscure RR bug?

TIA

Graham
