I've got a weird problem, I think due to the dropfile object in Max 5.
Basically, it is rather picky about which folders it will accept and use to populate a umenu...if I drag in a folder of sounds, it will sometimes not accept it and say "buffer~: /foldername/: can't open" in the Max window.
The strange part, though, is that it will accept every file in that folder individually and load it into the buffer no problem. It just doesn't want to accept that folder as a whole. That same folder loaded fine in v4.6, as well.
Other folders of sounds work no problem, and I can't see any pattern. Here is a test patch if anyone wants to try it out. Any suggestions would be great, thanks.
