Sorry to hear you are beepless. Mine is beeping away with abandon.
It's working for me -- OS X 10.10.3, FileMaker Pro Advanced 14.
I tried it with an existing application, created originally in 13, and with a little test app created originally in 14. It's working in both.
Thanks ch0c0halic and Jim for your replies. I gave my computer a restart and all is working again!
