FMP 11 Signon Warning

[John Chamberlain]

About 3 months ago I tried to open an app and was greeted with a message stating:

"Do you want the application “FileMaker Pro Advanced.app” to accept incoming network connections?"

There were Accept and Deny buttons at the bottom, and there was a warning about what would happen if I denied the question, like this:

"Clicking Deny may limit the application’s behavior. This setting can be changed in the Firewall pane of Security & Privacy preferences." I can't seem to find the referenced Firewall pane.

I find that if I click on Accept or Deny the app opens OK, but every sign (of this app or any other) on has this same thing happen.

How do I get rid of this?

It's a Windows firewall setting.  You can set up a rule in the Windows firewall to avoid this, or turn off the firewall on your computer if you have a firewall upstream in the network.
