That shouldn’t have happened of course! You should be able to use the Ctrl-z combination to undo a mistake. We’re going to look into the matter. Sorry for the inconvenience.

I had the same problem yesterday!

me too :)

I found this out the hard way, too.

Ctrl-Z was not what I expected, either! It undid several steps at once and reset all doors and windows to their original orientation. I assumed that keyboard shortcuts just do not work.

Same problem.. I wanted to undo the last change & it wiped out a whole series of changes, including all the text boxes I had added. DONT USE CTRL Z

I agree!!!
