When we use Zionworx with a PowerPoint Presentation of 20 or more slides (Sunday 15/05/2005 we had 26 slides in total), when we restart the PowerPoint after displaying one of the hymns/songs from Zionworx to cut back into the PowerPoint order of service the PowerPoint always reverted back to slide 21 and not the desired slide (for example the slide for the Benediction).
To let you have an idea of how we use Zionworx and PowerPoint together we have a welcome slide from PowerPoint which is started from the 'play' buitton on the left hand side of Zionworx. This welome slide is displayed until the words for the first song are required and at that point the PowerPoint presentation is stopped to display the song words as previewed in the central panel of Zionworx. After the song is finished the PowerPoint is restarted on slide 2 to show the next section of the service (could be opening prayer or a Bible reading). This pattern of stop starting the PowerPoint presentation continues through the service -- and only when the slide number that we require goes to 22,23,24,etc then the problems start and the PowerPoint presentation restarts at slide 21. If the whole PowerPoint presentation stays within 20 slides in total then this glitch doesn't happen.
Hope this makes sense and someone can shed some light on why this is happening.
