BoneArmature Runtime Error

Hi,

Whenever I link a set of movieclips together with the bone tool which are inside a containing movieclip, and also set the type to “runtime” instead of “authortime”, I get this error when published.

“Runtime symbols with skewed matrices should be wrapped in a movie clip”

What does it mean? I need the type to be set to runtime so I can use scripting with it…

Thanks.
