It sounds to me like it's not an excel problem. It sounds to me like it's a
windows permission problem.

You may want to post to a windows group and include the version of windows that
you're using.

ps. Did you try that KB article?

Yes well the opening and closing thing, I agree seems odd. Its like
something is closing it like a AV program. But Im fairly certain thats
not it. I have not tried to reinstall, believing perhaps foolishly
that, that will not change anything??

I can tell you that I have fixed it (I think) by doing the following.
I made the user a "Power User" on that local machine. Again showing
that it is obviously some sort of permission issue. Of course anyone
else who wants to put their 2 cents in Im happy to oblige, if you want
to make a stabby motion at it. Anyway, the power user option is one
way of resolving it I suppose.

Thanks.
