With Web Shield enabled, MSN and Yahoo are rendering weird and slow!

[ratchet]

Instead of the normal layout, it is mostly text, although there are a few images but still the format it strange.  I stopped the Web shield and all was normal.  This is on a Vista Home Premium, SP1 laptop.  Other security Mamutu, Online Armor and Sandboxie (although does the same thing not sanboxed).  Ideas appreciated!
