Thanks Milon<br>1. At first, it was a new file. I later found that it did save. I re-opened it the next day and used it in a service. At the very end of the service, I saved it again and the problem re-occured. You can't close the software normally. You have to use the task manager to quit.<br><br>2. I was trying to save it in a folder on the desktop. This is my usual folder which I have used many times before with the previous version of openlp V2.43. <br><br>3. I have never noticed this error before.<br><br>4. No, this was a typical openlp session.

Another error I have noticed is that whilst I can use the CCLI song import wizard to import songs, it very often crashes as I am using it. This is kind of frustrating as this was the only reason I upgraded. V2.43 finally got to the point where it would not let me use the CCLI song import wizard. <br>
