Jim,
I have not yet tried to load older files. I just purchased the Z1 and loaded VW2014 clean and ran the SP1 update.
Then I created a new file with a simple rectangular foundation, slab, and walls.
Just now coming back to take a look at it, I see it released selecting one of the walls and lets me select whatever I want. (Good.) But when I select them, the OIP says "No Selection" so I can't do anything to them. That's in Top/Plan view.
I switched to Top view and the OIP shows the wall info but then the selection is stuck again on one wall and won't let me choose anything else.
Flipping around the different views, I can get different things to happen but inconsistently. One time it will work, the next it won't.
