Disable Found New Server popup on client side

Hi,
Is there a way to disable the popup the user sees when he connects his client machine to another network running a UrBackup server?

We’re running with 1.4.x clients and 1.4.x server but want to do some testing with 2.0.x server on the same network.

However, if we set up the the second server, clients will see the popup saying that a new UrBackup server has been found and this will likely confuse them.

I’d like to be able to disable this popup if possible but don’t know if that’s possible. Thanks.
