Build and Run no longer available

[Alienspecimen]

I just wrote a simple program that displays on the screen a personalized greeting.

I then started experimenting with adding comments and moving the characters. Suddenly the "Build" and "Build and Run" buttons went gray and are no longer available.

I restored the program to condition when it was running first, then tried saving, closing the file and reopening it, but it did not help.

What did I do wrong?

Thanks in advance.

This happens when your program is still running in the background, even if it displays nothing. Just kill the task if it's the case.

It worked, thank you very much.
