Hi Chris,<br><br>Unfortunately this is largely unavoidable. It happens because OpenLP has to tell PowerPoint to stop presenting, to close that presentation, open the new presentation, and then start presenting the new presentation. As you can imagine, depending on the speed of your computer and the size of your presentations, this can take a little while (Windows 8 itself is known to be sluggish too).<br><br>The best solution I can propose is to set the background of the desktop to be black. That way there's not as much of a disjoint when the presentations switch.<br>
