Your iPad is slow, you click on items and it just outlines them. If you double or triple click an item, it may select it or it may not.
You may have an iPad that is in Voice Over mode. In my case, I had the volume down the whole way, and was not familiar with what Voice Over looked like when activated. IF you triple click the home button, it should toggle the iPad out of Voice Over mode. That setting is controlled in the Settings area.
