Hi Laurant, Thanks a lot for your reply. And perhaps I misspoke somewhat - I'm not trying to implement full drag and drop within my application, but only receive simple filename drop events that originate from outside the application. I think that it's just a matter of adding a few extra delegate mappings, but I don't understand how to "extend" more mappings into the hotcocoa wrapper classes.
Perhaps instead I will try to build from source and add the mappings there, and use a local build to test with. If a miracle occurs and I can figure it out, I will submit a patch. :-) Thanks again!
