Issue with the track editor

I used Cubase to make a full composition for work (yay!) but now I’m suddenly having an issue where I can’t just click a measure into the track editor like I used to. Now I can only click the pencil icon and make a portion of a track that does not snap toward any beat.

I need to be able to use the pencil icon to double-click in a measure in a sensibly place like it used to do. I messed with this for a good hour and can’t figure this out and Cubase is unusable in the meantime.

Okay . . . I guess it was the “snap” button. X.X Fixed, I guess.
