Baboosi,
One of the other problems with all the javascript editors is that objects are not selectable in Safari. I have used tinyMCE and that doesn't work well either with Safari.
On a side note while doing some testing last night, I noticed that on the latest FCKeditor, Safari will actually load it into the full window after about 6 to 7 seconds... so if you open and wait, it does correctly expand but objects were still not selectable.... so you can't select and resize and image or change the image attributes once it is in your content.
