iPad: the [Done] button is missing!
If you are running BuildCalc on an iPad and the [Done] button is missing on the “enhanced” and/or the “advanced” function screens, here is what is going on: Older versions of Apple iOS have a bug that prevents screens like this from being displayed correctly WHEN the screen is locked in landscape orientation. Usually, one would lock the screen in landscape orientation for a reason, so I’m not going to tell you the fix is “unlock the screen orientation”. Rather, the easiest fix is to update to the most recent version of iOS. The next time you go to sync your iPad with iTunes, iTunes should automatically ask you if you want to do this.
