Banner ads placements changing on clicking ads.

[zarnaagames]

Hi,
I am displaying banner ads at bottom. If I click on banner ad then one window opens and if I press 'Done' or 'X' button on that window then my banner ads placement is changed to center and then nothing is clickable on screen(I guess the view is still occupied by full screen ad). After some time(after ad gets refreshed) it come to bottom but still I cant click on any other my games buttons on screen.
I have to restart the game.

This is happening in portrait mode(I dont know about landscape mode)
I need to display ads at bottom location in portrait mode. Will you please have a look into this bug???

Here I am attaching screenshots. Please let me know as soon as possible.

Thanks
