Anja, my experience with b36 is that you can’t append to a file that’s currently open — are you creating a file and then trying to append to it right away? Note that your editor can be open, just not the file itself. I’m not sure if the same applies to the Tiger version, but it is consistent under Panther with several different editors.

Nathan, I’m not sure you’re right about Mac-aware editors. I’ve been creating files with touch and appending to them successfully, and I can’t think of a more plain-vanilla way to create a file than that. (In fact, since I haven’t been able to hunt down the elusive Create File QS functionality, my unseemly love for touch has been renewed.)
