Trello API authentication popup not closed

Question

I'm trying to demonstrate the Trello API but i'm having issues with the authentication procedure.

var ConnectToTrello = function () {
//console.log("Authenticating");
Trello.authorize({
    type: 'popup',
    name: 'Outlook Trello Add-In',
    scope: { read: true, write: true, account: true },
    success: authenticationSuccess,
    error: authenticationError
});};

This opens a popup where I can do the authentication, then I get redirected (in the popup) to https://trello.com/1/token/approve and nothing happens. The popup is not closing.

Any help would be appreciated.

I had the same issue until I tried running the ConnectToTrello function from a button. If you create a simple page with that javascript snippet being executed in the <script> block it exhibits the behaviour you describe.

However, if you add a simple button with that function as the onclick event handler, then it works just fine.

<button onclick="ConnectToTrello();">press me!</button>
