Cannot magnify scorecard for viewing

[kbum]

When I'm on the "Game Info" screen and select one of the scorecards, I can double tap or use my fingers to magnify the scorecard to see detail
But when I'm scoring the game and select the scorecard from the game settings screen, I cannot magnify it. Am I doing something wrong?
I have an iPhone 3GS on ver 3.1.3, iScore version 3.09.141

Use two fingers on the screen at one, and Pinch / Reverse Pinch (separate the two fingers) to zoom in/out in the game scoring screen.

Sorry, I forgot to mention that I do use my fingers to pinch/reverse pinch. This works when I view either of the scorecards from the "Game Info" screen. When I'm scoring the game and go to view the scorecard for one team, it may work, If I then change the view to the other team to check their scorecard, that seems to be the scenario of when I cannot magnify to see detail.
