Then maybe I wasn't clear. Here's an example:
You see how "Unanswered Topics" does not have a submenu. Neither does Downloads. On the PC, you click once on "Downloads" and you get to that page, as expected. On the iPad in landscape mode, you tap "Downloads" once and all you get is that little white arrow pointer point to Downloads, yet you're still seeing the Unanswered Topics.
That's not the expected behavior from the user.
The expected behavior is that you tap "Downloads" once and you load that page (and, if Downloads had a submenu, it would display that submenu at the same time).
