Cisco Firewall :: ASA 5520 Webpages Will Not Load Correctly

I recently implemented an ASA 5520 HA pair with CSC-SSM-20s in each non stateful per cisco.  The CSC management sits in a management subnet 192.168.4.0/24 with the management interface of the ASA as its default gateway in the same subnet.  Ever since the implementation frequently webpages will not load correctly, the formating will not look right and pictures will be red x.  If you hit f5 to refresh the pages loads fine.  If I add a deny any any eq 80 rule before the permit any any eq 80  the issue appears to go away.  TAC can't seem to find anything worng.  All we want to do is use a simple web content filter with the check boxes in the global filtering policy.  ASA is running 8.2(5) and CSC is running 6.3.1172.0.  Everything else works fine SVC and rules and such.  [code]
