Thank you pinoc, the odt and doc files are fine, OO does open them, BUT, when I make a change to the file, OO will not save it or anything else,it just freezes up and has to be killed to close. OO worked flawlessly on this machine for the past couple of years and only after the last couple of updates has developed this problem. I'll try to go back to 3.1 and see if that helps. Thanks for your assistance.
