Ever since I had Powerpoint 2000 for some reason the default font has been set to Dixiland (not very informative...) and line spacing to 0.8. Every time I open or copy presentations in a newer version of Powerpoint this is copied. How to change this seems to be specific for each PP version. 2000 used to have an option to check "use this as default" in the font format view. So how do I do it in 2010? I am using text boxes, not templates from the Slide Master.
