Successfully installed IOS 7 on 3rd Gen iPad a couple days ago. Opened App Store and there were 3 updates. Hit the Install button for each and each was installed. Opened App Store this morning and those 3 updates still show in the Updates tab but with an Open in place of the Install button. Thought once an updated app was installed the update tab would be blank. Have closed the App Store and even rebooted my iPad. Also did a search for IOS 7 and that search will not disapear even if I delete it when I reopen the App Store it still shows in the search bar. Are updated apps supposed to stay in the UPDATE window even after they are installed? Thanks.
