That article isn't intended to fix this error.
I have one machine out of 3 dozen or so with this issue, and haven't solved
it. Maybe I can give it another try tonight. It is in use during the day,
so I can only play with it outside of work hours, and I tend to spend time
in these groups rather than getting real work done--I have tried a great
variety of things--I am not aware of anything about this machine which is
significantly different from other machines in the same office--I know them
all quite well--software, upgrade paths, etc.
I don't have a fix for this issue.
