Yes, it runs it , but only the first time.
What i mean is that, if i haven't already pressed F9 (or click the button from the top bar), it does compile the program (i can see several stuff being written down on the Debugger window), but after a while it disappears. If i press it again, nothing will happen, except if i change part of the code (delete a ";" for example), then it runs it again and it shows me the errors.
How do i find this "don't send" windows dialog?
(Thanks for the answers mate!)
