Mill window surface selection for finish mill

I have a plate with several openings and some angled bosses and radii on it. I created  a mill window and used a mill->finish sequence which handled everything well, except it retracts frequently to skip the openings in the part. I made a copy of the surface and removed all of the openings, and redefined the mill window to the copied surface. The problem is the Mill->Finish still sees the original model and not the added surface. Thoughts? (Original part is an iges in case it matters).

Ok, I ended up copy/ pasting all of the surfaces and eliminated all holes and openings (using a 2nd ref model) , solidifying it, defining a mill window to the new solid copy of the part. Now I could use the finish routine on the new solid surface.

I tried the volume mill and it would have gotten the job done but I liked the tool paths I was getting better with "finish", except for the opening issue.

I am going to mark this correct but if someone has a solution that involves less work please feel free to share.

Josh,

The only way I have found to skip the openings is with a mill volume instead of mill window. I rough pockets and use the roughing routine with a mill window and to finish pockets I use a mill volume and with the parameters set to spiral and faces only with wall stock to keep the tool off the wall then create another sequence with the parameters set to follow hard walls and profile only to finish the walls. the mill volume fills in the holes so the cutter passes over them.

I have tried using the finish routine but as you say is tries to avoid openings but sometimes it's more efficient to just cut over the openings.
