[PD] Writing file to folder on OSX

[Si Mills]

HI

I can't seem to write a file into a folder using [writesf~]

So when I click the [open -bytes 3 /audio/foo.wav( message,  
presumably  it should create a folder called "audio" with the file  
"foo.wav" in it?

.....But it doesn't do anything.

Just doing [open -bytes 3 foo.wav(  works fine and creates "foo.wav"  
in the same directory as the patch.

AM I misunderstanding this, or is it a bug?

(on OS x 10.5.1, Pd 0.40.3-extended)

thanks
S
