When the reverse view button doesn't work, I use the spacebar on the keyboard. Does the same thing. Actually, the mouse I use now has thumb buttons that I programmed to act as the spacebar so at home I don't even use the reverse view icon on the screen. At work, I keep trying to hit the reverse view on my mouse but it's not there LOL.
*edit
Not more than 2 holes later after posting the above, at work the on screen icon would not work for reverse view. #18 at Kiawah, which at Kia there are many spots that reverse view won't work anyway but not where I was after the approach on 18. However, the spacebar worked just fine to show reverse view.
