When I close the project it locks and I can never edit again. If I delete pprlock the files within the project disappear. When I try to disable project locking, it won't let me, please help I'm so sick of this.
Are you using a Team Project then? And I must say, I'm not familiar with that screen you posted. I've done a lot of Team and Productions in collaboration for a couple years now. So ... I'm perhaps as puzzled as you.
And I have many times deleted the prprlock files without anything happening to the project files. This is ... very odd, somehow.
