Have you used a sniffer to investigate this?
Is the manager listening on the loopback interface (127.0.0.1)?
Does your machine has such an interface?
Is the SNMPv3 configuration correct on manager side (i.e.
for MIB Explorer the user SHADES must be configured and
the "Principal" check box must be checked)?

Do you have configured a trap receiver on 0.0.0.0 interface
and checked the principal option?

Seems to be a configuration problem...

Not really. What means "strip down" exactly?
Most likely something important is now missing...
