If this is the same problem we were talking about before when the software update first came out, then what you have to do is click and hold the notification bar along the top, then drag your finger all the way down so that the thin notification menu is pulled down and takes up the entire screen. From there, you'll be able to click on the icon.

It took us all a while to figure that out. I know I used to always just go to the home page, then hit Menu and choose "Notifications" in order to see the notifications. But, we eventually figured out that you could increase the size of the notification bar to the whole length of the page by clicking and dragging, and then you could select the notification items directly.

Does that help?
