Not able to set compile flags in xcode 4.3.3 in build phase/compile sources
===

In Xcode 4.3.3, for some reason, I couldn't set the compile flags for few files that I wanted to skip compiling for ARC. 

I basically did Target->Build Phases->Compile Sources, then select the files and hit Enter. 

When hit Enter or even just double click on a single file, I don't see a dialog pop up for me to enter the compile flags.

Anyone has the problem? I am using retina Mac Book Pro running on Mac OSX Lion.
