Hello,
Thank you for advice and suggestions. As for OpenOffice, later on I removed it and, by means of removepkg I removed, one by one, all the packages that had been installed along with OpenOffice, but when I restarted VL, no GUI was available any longer. So I restarted again choosing TUI and reinstalled OpenOffice which came with all the packeges that I removed before. Everything is OK again, but I couldn't do what I wanted, restoring the system as it was before the first installation of OpenOffice, in order to be able to install it alone without that lot of dependences

However I like very much VectorLinux all the same.
Best Regards
