Utilities Menu "timeout"?

I have a few programs that I send files to in the Utilities menu- Sound Forge, RX4 and now RX6. In all of them, if I'm in there too long editing, when I save the edit and go back to Sonar, it won't give me the dialog box asking if I want to load the new version. Is there some setting somewhere where I can change this behavior?
 
Thanks,
