I am working with Safari 3.0.4 and there is the list of specific things that don't quite work:

 

1.  Insert Form doesn't seem to do anything.  As far as I can tell, nothing shows up in the UI and I don't see anything in the code view.

2.  Insert Layer doesn't do anything either.  As far as I can tell, nothing shows up in the UI and I don't see anything in the code view.

3.  The absolute position button always looks depressed and doesn't really do anything when I try to apply to an image.  If I go edit the code manually, I can enable absolute positioning, but then I can't drag the image around in the UI.
