"UNDO" again not working.

For some reason the Undo is not working.
This is happening frequently and I don't want to keep re-starting AC13 all the time.
Do you have any clue why is this happening?
How can I fix this problem?
Need some help.
Thank you

UNDO will only undo back to your last Save -- once you have saved your file, you can no longer UNDO. Also, check your "Undo Limit" within your Work Environment settings (see attached).

Even though I draw a new wall I can't Undo.
Then, If I erase my new wall I can get it back. It's just so scary not being able to Undo some important things.
Is this just me?
Thanks a lot for your concern

Assuming your "Undo Limit" is greater than 1, its sounds like there may be something wrong with your installation. I would try uninstalling and reinstalling AC.

Getting the same thing. Seems random as to when it occurs. Once instance of AC is fine, another instance all of a sudden no UNDO. Not good.

Simply closing out of a project and reopening, without restarting AC and it's back on. Doesn't make any sense and no way to know its happening until you try and undo something.

Some commands will delete your undo queue making it impossible to undo after that point.

I got the same thing a couple of weeks ago, happened for a few days then stopped. Restarting ArchiCAD fixes the issue. I agree it's very problematic.

Is the lack of undo in a second archicad? I've found that if you launch a second archicad, that file will not allow an undo.
