Don, there are a couple of things to check. Run OpenLP click on settings, then configure OpenLP, now select Themes, there are two settings here, first is global theme, this is often set on a new setup as default, which is white letters on a black background. The second setting is called Theme Level, there are three options here, Song Level, Service Level and Global Level. If this is set to Global level, then themes will not appear to work. Set this to Song Level and see if your themes show up. <br><br>I use two machines, and I find that what works best, is to put them side by side, and go through the settings and make sure they are all the same, it's not uncommon to miss setting one little thing, and it seems to not work at all. This isn't only OpenLP, but pretty much any piece of software that works in one place and not another.<br><br>
