I have been having the same problem, I guess since the last update..
My says it has to shutdown because of urlmom.dll.. I have registered it, and
looked and emailed on the MS site, but no help yet.. I saw another post
somewhere on here to disable/uncheck the third party browsers in the
"tools/advance tab under browsing) Which seems to have taking care of the
problem... But I would like to have it the way it was!! Hope that MS comes
up with a update/fix
Thanks
