Touch not working in top right

I am facing a ridiculous problem in Corona. I haven’t faced such problem in last 3 years. 

Touch/Tap event is not working in the top right portion of simulator. I made an android build and tested in phone. Not working.

I placed a ui button in top right of the screen. When i click it nothing happens. Event callback function is not calling. But if I change just its position to any other places of the screen it works fine. 

I added a runtime listener to check it more deeply. I prints log in everywhere I touch or tap. But when I touch/tap on the top right portion nothing is printed (event listener is not called)

Are you using the director class?

Are you using director for scene management? If yes, you need to search this forum for messages on how to update director for graphics 2.0.
