problem with extrusion

 From:  Raoul
Hi Michael,

I try to extrude this contour.

When I extrude downwards, the whole countour is extruded. When I extrude upwards, only the inner contour is extruded.

Any idea what goes wrong, or what I am doing wrong?

I work with the beta V3 from 6/11/2012.

Hope you can solve the mysterie.

Kind regards,
