So, I hope someone can help. I have to do a presentation tomorrow, but for some reason when I run the slide show in Impress (OO's version of Powerpoint) the screen comes up black! I can click through and get to the last page that says click to exit the presentation but nothing else will show up! I've made sure that none of the slides are hidden, that they're not being covered up by anything in the background ect. I've even tried opening a new version of Impress and making a new slide, but the same thing keeps happening.
