Alpha updated

[Bill Sun]

I successfully rebuilt and bootstrapped the VM. 
However, right after the bootstrapping process, when I
tried to execute the save image command, I get this
error message:

========================================================================
Hi, there!
Please save your image now, (eg. "Image saveNamed:
'slate.image'.") to
eating this bootstrap.
Slate 1> Image saveNamed: 'slate.image'.
The following condition was signaled:
-1 is not a key in {Nil. Nil. Nil. Nil. Nil. Nil. Nil.
Nil. Nil. Nil}
========================================================================

I tried some simple additions like "1 + 3." and they
all end of with the above error message.

Any ideas?  Did the windows files get out of sync?
