Hi,
I had the same issue – I installed a fresh copy of 3.3 on my local Mac and it freaked me out, namely because when I upgraded from 3.2.1 to 3.3 on another local instance I didn’t see it.
The fix eulamue posted fixed my problem. Just wanted to pass my findings so others will know it works.
I too am having some issues with slowness; but not always. I am trying to narrow it down before switching back to 3.0.
I was curious how you check the size of the home page; also is there a way to have JavaScript cached?
