Help!!! Iexplore err in Istbar.dll

Any idea what this is?? It happens when shutting down! New computer.
Only "hibernate", not usually shutting down. Does this have something
to do with it?? Any other ideas?? Also downloaded "popup stopper"
from Panicware.com but don' t know if this has anything to do with it
or not. Any other ideas???? TIA!!!
