There have been many posts recently concerning the enter key not working.
Unfortunately, nobody has a definite answer to the problem. It seems to be
related to a recent "hotfix" ( KB828028) but, it only effects some machines
and not
others. After some discussions in the newsgroups and person to person with a
few tech people, I/we've come to the conclusion that there is a conflict
between the hotfix and some software that is installed. It may be the brand
of keyboard, the AV program you are using or a particular screen-saver, etc.
There is not enough information given by those effected for anyone to be
able to determine a relationship between the computers that are effected.
My machine was not effected and, evidently, none of the MVP's has had a
problem. Otherwise, by now, one of them would have come up with a solution.
There have been people report having done various things that seemed to cure
it on their machine but, they vary so much as to make no answer to the
problem clear.
If you have an HP or Compaq machine, the following link may be of interest
to you. I don't know if it would apply to any other machine.

You might try uninstalling that "hotfix" but, that still doesn't solve the
puzzle.
I realize, this post is not much help but, perhaps it will inspire someone
more knowledgeable than I to investigate the issue a bit more thoroughly and
find a solution to the puzzle.
