We have using OpenLP for some time, about a year ago we made a switch from projector to tvs. In doing so I found that all the stock themes and those I had built previously did not work any longer as they did not "fit" the screen. So I began creating new themes with 16:9 as the image sizes... Now suddenly today I open up OpenLP and none of my newer 16:9 themes fit the screens, however all the old ones do now. NO changes had or have been made...
Do I now have to rebuild all my 16:9 backgrounds?
What am I missing?
