I have tried boolean in various situations on windows and mac osx.
On windows mostly I got those extraneous edges too, while on mac
osx everything seems to be ok.

But another problem appears on both Mac and Windows. If I've cut out
some simple cubes out of another cube (i.e. windows in a wall),
sometime it stops to be possible and I get always get the message
  "Both mesh must be a closed mesh".  All the meshes should been
still closed, because, I just made a boolean difference with simple
cubes (example: wall with windows). I have controlled the meshes and
couldn't find any hole.
