Touch Screen not working for Google Maps or Youtube

Just the other day I started noticing a weird issue. The touch screen is non responsive for the top banner on Google Maps (the location field, the transit buttons, the edit button). The touch screen works for the rest of the application. I can move the map around and use any of the buttons along the bottom. It renders the app pretty much useless as I can't enter any new addresses in.

I also noticed a similar behavior in Youtube. The "Done" button can not be pressed. When I go to the Mapquest iPhone page, I get the same issue...buttons in the top banner do not react to touch.

At first I thought it might just be a defective screen but other buttons (such as the Text app button in the same location) can be pressed and respond to the touch.

I've rebooted and even restored to a point before this started happening, but no change.

Has anyone ever seen this issue or is anyone experiencing it with the above apps? Any ideas?
