Unable to enter text into Arduino ide on my Mac?

So, I have a weird issue with the Arduino IDE and my Macbook Pro. I can open up the IDE, copy and past text to and from it, compile and upload, but when I try to type all I get is the system beep. :frowning: I un/reinstalled the app and rebooted the computer but to no avail.

Although I can build in TextMate and copy it over but that is kind of a pain for library items. I still am able to work with my Linux laptop so I'm not freaking out but this is still inconvenient. If any one has any idea on how to fix this, it would be greatly appreciated.

Thanks,
Dean

Go to the Arduino -> preferences menu.
Make sure the "use external editor" is unchecked.

That was it!!

Why would one need to have that box checked anyway? It seems unnecessary.

Thanks for the quick reply.

The clue is in the name.
When you are using another program to edit the source code. Maybe one with better search / edit functions or one that you have used forever and you like.

Yes, but it seems you could edit in another program with or without that being checked, then copy paste. I think I am not understanding something.
