After updating iTunes to 11.0.3 today it appears that the Update Apps button is missing from the bottom bar. It was just next to the Get More Apps button. The sidebar indicates that I have an App to update but I am unable to do that because of the missing button.
NEVER MIND! Thay added an Updates button towards the top under the window. Why do they do this stuff? Everyone gets used to a location and they pull something like this. Leave it alone unless it has to be changed.
