I am not sure what the issue is then. Maybe because it is in a bpatcher? The specific patches that i have an issue with are mlr pathces. Just download any mlr version from monome.org and none of the drop files work with the beta. All you have to do is try and drag a sample over to the dropfile and it shows that you cannot drop it. It only works when you open the bpatcher for the file list and then unlock the filedrop object and drag the sample onto it.
