Can't change number of vertices/segments on just created mesh I have a problem with changing segments of a newly created sphere. A window where I can change it is transparent and does not respond to any clicks. This problem is with any mesh I create. There is already another mesh in the project in which no problems were observed.



Every time I click this window just disappears. Thanks!
Maybe you need to reactivate the Global Undo option in the Preferences > System.
