Can't exit keyboard – MyScript Stack - Handwriting Keyboard Review

I can access the Stack keyboard through the world icon from other keyboards, but I can't find ANY way to exit. Using the script keyboard is interesting, but not at all up to speed. Since I can't get out of the keyboard once selected, I've had to take it out of rotation. This is a significant oversight.
