To sum up: The only problems remaining are: * That I can't open a file directly (I have to open excel alone first, then the file). I can live with that and I guess most would as well. * That all hyperlinks disappear, and that excel crashes when I try to use one. * That I can't install any add-in. I hope what I fixed will be usefull to some of you, and that someone will be able to help with the remaining issues. Thanks
