Promising app suffers from iresponsive UI

The app is pretty promising. It’s completely free meaning you can use it as if you are on Facebook. Totally no restriction here.

However, the settings UI is basically irresponsive.
When I open the drop down list containing “about", “settings”…, the list is basically not responding.
If I click on “settings”, nothing happens. No window pops up at all.

Once the UI bug is fixed, the app should be a gem.
