Here is the right one.

Thank you, davesexcel; I did find some helpful things with the search you suggest.
Thank you, MarvinP. I follow the steps you mention and moved ahead... some; but see the result in the new file attached.

Thanks a world, MarvinP, for your efforts on my behalf; and I regret that it led to some trouble for yourself. As for your latest suggestions, this:
-The first one, about your link from yesterday: I studied it, yes, but it was no help to me bcs it starts with my problem already solved. I mean: His Fig 1, all right, mine is exactly the same. But his Fig 2 shows the Project and Properties frames in the right place and already locked (without their icons for Full window and for Minimizing). And that's precisely what I never get: I arrange those two frames exactly like him; but as soon as I check them in Tools->Options->Docking, they dock all right, but they've changed their size to full width, and any Code frame after that remains floating, as in the fig. I attached yesterday.
-The link to the Register: That I don't dare to attempt, bcs I'm not knowledgeable enough and I fear I'll cause greater damage elsewhere.
So, I'll have to live with my poor state of affairs.

Thanks again for following my query to this point.
