Unresponsive top buttons in nook app

[jeregano]

Ihave CM7 in my nook color use the nook app to read books. I am finding lately that the buttons in the top bar in the nook app (shop, search, options, etc) don't respond to my touch. It doesn't in portrait it landscape. I have no problems with the edges of the screen otherwise, just in the nook app. Thoughts?
