I have installed the IntelliJ IDEA 12.1.2 CE on my Macbook Pro running OSX 10.8.3
Suddenly it refuses to open any existing or newly created project.
When I start IntelliJ then the "Welcome to IntelliJ IDEA splash screen appears, where I can open, create, import projects.
When I open a project, I can select it, and it loads the files, but then the Project window does NOT open and the splash screen stays. I have no chance to see the project window.
I uninstalled and reinstalled IntelliJ but no change here.
Does anyone has an idea how to fix this?
