I updated my iTunes a few weeks ago.
I have my music on an external HDD and stream to my stereo via iTunes.

After the update there was a problem that iTunes would not stream to the stereo, but I found the solution to allow incoming network connections.

Now, everytime I start iTunes I get this message:

Do you want the application "iTunes.app" to accept incoming network connections?

When I click Allow I had to enter my Admin login name and password.

Is there anyway it permanent to allow incoming connections?
