So that's what happened! I tried the Kamikaze mode the other day and couldn't figure out why my bottom lines were disappearing. I started pressing Ctrl+A Ctrl+C in between typing as a precaution.
The normal mode is funny. I hadn't noticed the pause button (you can tell how attentive I am) the first time I used the tool, so when my husband called in the middle of a session, a song about banana phones interrupted him.
The lesson for you all: Learn the settings! Don't be like me.
