The app worked well however, I had turn off the phone to stop the app.
I used this app a little while ago and it was great. I could really look around each 'class' area. Since then so many hyperlinks have been inserted to activate as soon as you look at them that you cannot stare at the most usual eyelines such as down the aisle because as soon as you do you are bounced into another class etc. This spoils it and could be corrected by moving the links slightly.
