Timer Job adding item to List not firing Event Handler, but Event Handler works fine when item entered manually. Why?

Hi,

We have a Timer Job and an Web Scoped Event Receiver on a List called "WeeklyWrapLog" (uses content type). When I manually enter an item on this list it triggers fine and adds another entry on the same list. However, when the Timer Job creates an entry in this list the event receiver does not seem to fire and only the timer job entry is written. I cannot debug as on another machine.

The code for Event Receiver is:   

<?xml version="1.0" encoding="utf-8"?><Elements xmlns="http://schemas.microsoft.com/sharepoint/"><Receivers ListUrl="Lists/WeeklyWrapLog" Scope="Web"><Receiver><Name>WWLogCreatedItemAdded</Name><Type>ItemAdded</Type><Assembly>$SharePoint.Project.AssemblyFullName$</Assembly><Class>IntranetHomepage.Event_Receivers.WWLogCreated.WWLogCreated</Class><SequenceNumber>10000</SequenceNumber></Receiver></Receivers></Elements>

namespace IntranetHomepage.Event_Receivers.WWLogCreated
{
    /// <summary>

    public class WWLogCreated : SPItemEventReceiver
    {
        /// <summary>
        /// An item was added.
        /// </summary>
        public override void ItemAdded(SPItemEventProperties properties)
        {
            EventFiringEnabled = false;

            try
            {


                SPSecurity.RunWithElevatedPrivileges(delegate
                {

                    CreateTestLogItem(properties.List, "in Item Added");


                    if (properties.List.Title == "WeeklyWrapLog")
                    {
                       /* I commented out code here */
                    }
                });
            }
            catch { }
            finally
            {
                EventFiringEnabled = true;
            }
            base.ItemAdded(properties);
        }

        public static string StorageKeyToID(Guid storageKey)
        {
            if (!(Guid.Empty == storageKey))
            {
                return ("g_" + storageKey.ToString().Replace('-', '_'));
            }
            return string.Empty;
        }

        public void CreateTestLogItem(SPList logList, string str)
        {
            SPListItem item = logList.AddItem();
            item[logList.Fields["WW Edition Reference"].InternalName] = str;
            item.Update();
        }

    }
}

            SPUser user = web.EnsureUser("<my account name>");
            SPFieldUserValue oUser = new SPFieldUserValue(web, user.ID, user.LoginName);
            item[logList.Fields["Created By"].InternalName] = oUser;
            item[logList.Fields["WW Edition Reference"].InternalName] = wrap[wrapItems.Fields["WW Edition Reference"].InternalName].ToString();
            item[logList.Fields["WW Edition Date"].InternalName] = now;
            item[logList.Fields["WW Issue Number"].InternalName] = wrap[wrapItems.Fields["WW Issue Number"].InternalName].ToString();
            item.Update();

        }

    }
}

Just a note that some fields are read-only on this list and have been used by InfoPath I think as Internal names are GUIDS - not sure if this is associated to problem.  

Help would be appreciated.

Thanks.

John.
