[LVL ED] Level editor won't set a sound entity to a sound element

[Austero]

I have exactly the same issue on MacOS Lion, so it works perfectly with a text editor, but when opened with the level editor, the sound file name is gone immediately. I did set up the write privileges of the folder and sub-folders to "everyone", so that shouldn't affect it, should it?

Anyways, it works with the text editor, just a bit inconvenient.
