The problem is that this UIWindow stays in stack after Yoshi has been disappeared as Yoshi never removes this UIWindow from the stack and never makes main application's UIWindow keyAndVisible again. Yoshi just removes it reference to the UIWindow it created (see lines 100 and 111). It influences long term behaviour of the main application and also influences other libraries that creates UIWindow.
UIWindow contains method removeFromSuperview() - it should help potentially, but also Yoshi must make sure that UIWindow that Yoshi overlapped is key and visible after Yoshi disappears.
PS: I am not sure why to be presented Yoshi creates new UIWindow, and how IOS does not like modals (YoshiConfigurationManager line 69).
