NetBeans why do you disable Save?

I've started programming in PHP again for a new project I've taken up, and I've found that NetBeans upon noticing that the file has already been saved will disable the Save function. This is also disables the ?+S to save the file, which means when I am sitting there thinking, and I mindlessly tap the key-combo it makes my computer "ding" which is the default system beep sound.

It is my hope that eventually they fix it and just leave the save function enabled and if the file doesn't need saving they don't save it. That way my I don't have to listen to "ding" thereby breaking my concentration.
