Xcode 4.4 - Unable to add compiler flags to compile sources

Question

In Xcode 4.4 it seems I am unable to add compiler flags to individual source files. I am trying to remove ARC from a single file but I can not get the pop up to add flags. Double clicking or selecting the item and pressing enter does not work, also tried selecting multiple and pushing enter which does not work. I have tried with two separate projects, one of which I created with Xcode 4.4. Is there another way to manually add compiler flags to a source file? (I do not have an older version of Xcode to see how it stores the value [likely in the pbxproj]).

I found where the window was hiding. I had to drag Xcode pretty far down to the lower left corner of my screen as the pop up window was showing up and to the right. This made it completely hidden while full screen.
