Keyboard not hiding when parent.visible = false

[niall-slater]

I've got a menu panel with multiple text fields in it and I'm closing the menu by setting the panel's visibility to false. Unfortunately if the keyboard is open when I close the panel, the keyboard stays open. It also lets you open multiple keyboards on top of each other.

I've tried a few things but I'm not sure where the reference to the keyboard is - destroying the panel also doesn't destroy the keyboard, and it doesn't seem accessible through the TextField object. Any ideas?
