In an IntroJucer project, if you only change the “Compile” state and then re-export, Visual Studio is not notified that the file has changed. It is necessary to unload and reload the project in Visual Studio (2010) to see the state change.
This problem happens intermittently.
…but this is a VS problem, right? The introjucer just saves the files, there’s nothing it could do to force VS to act on them…
Hmm…you might be right about this. Still, it’s a royal pain in the ass.
