renovation palette gets inactive in 3d window (help needed)

[sityu]

In ac18, in some (particular) files, when switching to 3d window, the renovation palette gets inactive, so I am unable to set the renovation status in 3d window.
In floorplan (or in other windows), I can adjust it, as usual. Other project files are working well.

Actually, the 3d window's renovation status is independent from the floorplan: so in the 3d window, it switches automatically to "planned" status, instead of the floorplan's "existing".

Here is a link to the screenshots with explanatory comments on it. (in the upper right corner, you have to switch on the comments, to view them; the dropbox folder is public, so you can check it without signing up/in)

Any ideas, any suggestions?

Finally, I managed to fix it! (I swear, I've tried everithing, before.)

That's how I did:
1) saved a view, from 3d window;
2) in saved view, in the view settings, I was able to set the renovation status (originally it showed a "missing ren. status" (the 3d window has been stucked in a missing status); and at first I was unable to change it; but at second try, it worked);
3) all these procedure freed the inactive status in 3d window, so it works again.


Solved!

(I think it can help others, that's why I'm not deleting)
