No longer able to drop a file onto Mac Application Icon


I have a simple backup app, which allows me to created a copy of files (usually Xojo project files) which normally works by dropping the file onto the backup app and the copy is made. When I tried to build in the current version of Xojo, I got that inaccurate error about having two of the same and unable to determine which one (can’t remember the actual wording). I deleted the FileType (only) project item and added a new one and everything built fine, but the application no longer accepts dropping files onto it in the dock.

Does anyone know if there was there a change that causes this and if it’s possible to get the functionality back?

Thanks in advance!

Found it! It needs to be set in the File Types macOS Build settings (I expect that may have always been the case, but I’d forgotten!)
