How to completely stop R script in RStudio v1.3?

Before upgrading to the latest RStudio (I think from v1.2 to v1.3) when I needed to stop the existing chunk of code from running I would simply press Esc and it would completely stop.

In the updated version, it seems pressing Esc only stops the existing line from running. It will then move on to the next line of code, before I then need to press Esc again. This process repeats itself until all the lines of code have been interrupted with Esc.

Is there a way to stop all the back-logged lines of code from running at once, similar to the previous version of RStudio?
