What's Wrong?

esc key must stop claude and allow adding new instructions, instead of stopping all background commands! it
worked before as expected, but now after some update esc stoppes background tasks!!! I hit esc 5 times to tell claude something and stopped all background tasks. Totally not usable!
I am always correcting claude or tell something else, and don't need to stop background tasks at all!!

What Should Happen?

claude must stop and accept new input. not kill background tasks
