Kevin, I just opened 3.3.2 (you said 3.2.2, but that "may" be a typo)
Went to the Nutcracker tab
Clicked on the the Open Folder/File icon
Selected Create new Animation (and left it at 10sec)
and it is very blank
until
I select a few Display Elements
I click on the Insert Row icon
Then, I get Grid Lines. I still have to manually type in some Start Times.
