Bone display very wrong - unusable!

i am using flash ide version 10.0.2

hi there, i just put a screenshot . it is taken from the tutorial here:
http://www.layersmagazine.com/flash-cs4-animating-puppets.html

and you see selected an movieclip which should have bones, but instead of displaying the skeletal structure it is showing me just a dot in the left upper corner …

and the same when i draw a form on the stage, and select it and start drawing a bone inside … it just goes in to the left upper corner and looks bad

beside, the bones seem to work correctly, when i drag parts of the puppet
i can only moves the elements where they should … but the bones display wrong, please, if anyone had this problem also, describe a solution …

i will try to post it on some adobe bugreport site …

regards
ck
