What's Wrong?

I am using claude v2.0.21

I saw the new questions interface, not sure if I like it, but I see how it might be better...
Anywas I was typing in my prompt to answer, and the prompt was cut off by the limit of the width of the screen. So the entire prompt was not accepted. Had to widen the view to get the prompt inside.

What Should Happen?

I should wrap the text and allow me to change the prompt with the interactive IDE text editing enabled. I should be able to view my entire prompt.
