<p>Dear all,First of all, I want to thank all developers, translators, and other contributors for an amazing piece of software. I was able to use it for the first time very recently, and it cut my preparation time in half, compared to both LibreOffice/OpenOffice Impress and MS Powerpoint.Unfortunately, I was a bit confused by behaviour that I encountered in OpenLP. This behaviour was unexpected since OpenLP did not do what I thought it would do:1. There does not seem to be a way to end a service presentation session. I must either press the 'show desktop' button or close OpenLP.2. When a slide (in this case LibreOffice Impress) is shown from inside OpenLP, and then the presentation is ended, the desktop background is shown instead of, e.g. the next Bible reading or a blank screen.3. After a slide show (LibreOffice Impress) is ended, the 'blank screen' button does not do anything. I first have to click on a song or a Bible reading before the button works for me to blank the screen.Am I using the program wrong because I am a beginner? Or are these issues something the developers need to be aware of?Thanks in advance for any replies,Etienne(A grateful OpenLP user with version 1.9.10 on Ubuntu Linux 12.04)</p>
