Console can't connect after code exits in error

Hi!

I'm new to Pycharm but I'm happy with its layout and codeing in the editor (I'm using the CE version). I like to run my code in ipython so that I can check variables that were defined in the code afterwards and play a round with them. So I like the option that Pycharm can show the command line afterwards. However, when the code exits with an error, I can't use the command line afterwards. It just freezes. This is very annoying because thats the time when I need the command line the most to check what went wrong with the code (yes I know not standard but thats my way of debugging). Can you tell me how I can keep the console from freezing? Also is it possible to rerun the code in the same console session with a keystroke and without having to type %run ... ?

Thank you!
