Is there a way to stop compiling Blueprints?

Hi all,

Is there a way to stop compiling Blueprints?

Once started compiling Blueprints that takes quite long time, UE stops responding, sometimes including OS freeze.
This may occur while editing blueprints (ex: containing infinite loops caused by some default values).
And after restarting UE after freeze, the blueprint never opens. (as preview may take long time, I think.)
So, we need some chance to re-edit blueprint in such case.

Thanks.
