raoul For me, the error occurred when OpenLP first tried to load our splash screen and with File, Open Recent. I suspect that the Mac open dialogue sorts out permissions or is recognized by DropBox while direct calls from the app are not. It still complains about File, Open Recent.
Many Mac apps have to ask for permission the first time they open a file in DropBox (sometimes even to open files in Document, Downloads, etc). In my project developed in Freepascal/Lazarus, the standard Mac message opens, asking for permission. We didn't code anything.
I would put this way down the list of things to chase down. If I get a chance, I'll peek at the code, but I don't speak python very well.
I suspect that it may just be a matter of interpreting the permissions error properly and asking the use to open directly.
