Unable to edit Scala files in Eclipse...?

Hi Sean --

I cant edit any Scala file with the plug-in.. is this a bug or did I do 
something wrong?

Best,
Vijay
=====================================

I am working with Eclipse 3.2M:
Eclipse SDK

Version: 3.2.0
Build id: I20051215-1506
=====================

Just downloaded a fresh Eclipse install. Installed Scala plugin (2.1.6) 
from the website, created a Scala project (fine), created a new Scala 
file (fine). But now I cant edit the file! (The file is readonly.)

The error log says:
