Drop down with "Launch Web App" issue

I am logged in and when I go to the home page of Raygun I can see my name in a dropdown box. When I click it there is now a gap between the combo box and the menu that drops down so that it hides when my mouse tries to navigate to the menu items.

Which means that I can click "Launch Web App".

Interestingly I just noticed it works OK on these forums even though there is still a gap.

Using the latest version of Chrome.
