Enable Perforce in all IntelliJ windows

Question

For some reason, Perforce is working on one project window but not the other. Does anybody know what I have do to make intellij recognize that the current project uses perforce. I have checked the Settings -> Version Control -> Perforce settings. Settings are good, I was able to connect.

I am lost, any help is appreciated.

Answer 1

VCS -> Enable VCS Integration

Note that the this option is not visible if VCS Integration is already enabled.
