Stop on runtime errors in simulator

Hi all - I suspect I probably missed this documented somewhere, but I can’t figure it out and it’s frustrating me…
(I’m running the mac version of corona SDK)
When my code throws a runtime error (for example, trying to do math on a nil), the error is reported in the terminal, but the code continues to run until something more serious happens (which is usually the case when the bug is in a loop), eventually crashing the corona simulator, forcing me to close the terminal window and restart a new simulator session. How can I just have the simulator stop running code when there’s a runtime error?
Thanks in advance!
Scott

(I’m the OP)I haven’t seen this problem lately, I suspect for one or both of these reasons:
1 - I subscribed and have been using daily builds, I assume they have fixed many bugs since the last stable release.
and/or
2 - I’m learned enough lua to avoid the kind of mistakes that were triggering these problems. I was pretty new to lua when I was having this problem regularly.
