This one is simple.

CC Version:
All that have the paint program

Description:
When pressing 'e' to exit the paint program, the 'char' event is not cleared so the shell prints 'e'.

Steps to reproduce:
  1. open paint
  2. press CTRL
  3. press e
  4. look at the shell

Nice and easy one to fix adding a coroutine.yield() to the end of the program will stop it.
