change the severity of an event in HP SIM 7.4

Hi,

i'm running HP SIM 7.4 on a SLES 11 SP3 64bit box. I'd like to change the severity of some events. I googled around and found some folks proposing to change it in Options ==> Events ==> SNMP Trap Settings. I changed the desired severity (from informational to major), the WBI accepted it, but in the event log it continues to appear as "informational". If i edit the description of this event, the change is visible in the event log. Any ideas ?

Thanks for any tip.

Bernd
