I think I may be able to pin down exactly what is happening here.
When you run a powerpoint presentation, if you advance slides using space bar (or the buttons on the PPT tab) after you get to the last slide, PPT displays a black slide with the words 'end of slide show, click to exit' at the top. If you press space to advance one mor after this (or click next slide button) it seems to advnce to a further black slide, but indicates to ZW that the presentation has finished (thus only shows the start presentation button in the PPT Tab). The problem is that the PPT presentation window is still in the foreground (black) so the song lyrics are displayed, but hidden behind the black PPT display window!
To avoid getting into this state, click stop on the PPT tab whilst still displaying the black screen with the text at the top (or load up some song lyrics, as this forces the presentation to stop)
To get out of this state should you inadvertantly get there, you have to click start button on the PPT tab, to start the show again and then click stop on the PPT tab to stop it properly. This gets it out of its 'stuck state'.
To try to prevent this causing a problem for inexperienced users, tell them to click the 'loop continuously' check box before running the presentation, and you won't ever have this problem. Trouble is you need to do this for every presentation, and it is easily forgotten!
For the developers, I gues it just needs to grey out the 'next slide button' (and disable space/enter) when the first black powerpoint slide is reached and all will be fixed ?!! If you need anything else, to help identify the problem, just let me know.
