Wireshark-users: [Wireshark-users] HTTP web service traffic with large header

I’m having trouble getting Wireshark to recognize HTTP traffic from SoapUi. I’m sending a large header (hoping to reassemble the HTTP pdu and measure the size of the header). WireShark sees it just as TCP. It does see browser traffic as HTTP. I’ve trying a small header with same result.
 
I find that I can only get into PROTOCOLS within the EDIT/PREFERENCES menus sometimes. It looks like a bug. It will not work unless I have capture running and then only sometimes. I understand that I need to have TCP and HTTP settings within Protocols.
 
Is there some config reason for this ? I’m running this on Windows XP.
