Emmanuel,

You're amazing! Busy with work and still you find time for a new beta. Do you ever sleep at all?

I saw a typo: in 3D view it says Got to point of view, that's 1 letter too many.

With CTRL+ENTER, are you referring to drawing round walls? I can do that but with CTRL+CLICK 2nd POINT and then drag.

I'll try and test-drive this version in the next few days.

Hans
