Keyboard collapses on iPad when user types

I'm using two of the objects for a login screen. They work fine on the iPhones but on iPads the keyboard appears then collapses as soon as the user types. My app is not iPad native so it's just being scaled up. Any thoughts on how to solve this?

Start by reproducing the keyboard collapse with two JVFloatLabeledTextField objects in a scaled, non-native iPad login screen. Compare the behavior while typing on iPad and iPhone, then confirm the keyboard remains open during input after the issue is addressed.
