cfcookie problem between computers

I am migrating websites from a server using CF 8 to a new one using CF 10. In this one site, I have a query that looks up talent and then writes the resulting list to a cfcookie. On my computer with any browser it works correctly. My client uses the same browser as I normally use (Safari) and his browser is not updating the cfcookie with the new talent list after a search. They are very unhappy making me unhappy also. Any ideas as to what might be causing this problem.

In the application.cfm (yes, I know I should be updating to cfc but not enough hours in the day):

<CFAPPLICATION NAME="lil"

          CLIENTMANAGEMENT="yes"

          SESSIONMANAGEMENT="yes"

          SESSIONTIMEOUT=" #createTimeSpan(0,0,30,0)#"

          APPLICATIONTIMEOUT=" #createTimeSpan(0,1,0,0)#"

          clientstorage="cookie">

Setting the cfcookie:

<cfif isdefined('getTalent.recordcount') and getTalent.recordcount gt 0>

         <cfcookie name="tSearch" value="#valueList(getTalent.talentID)#" expires="1">

</cfif>
