For the past little while (perhaps since upgrading to the latest stable build) sometimes when I save my main.lua file and the simulator reloads, I will get a Run Time error message in growl and to check the console. But there are no error messages in the terminal display. A CMD-R reloads it with no error message in Growl.

Has any one seen this behavior? Do I have a bug I'm not seeing?

Thanks
Rob
