I’m having trouble working with Powerpoint files. Can you give some help?

Presenter makes a connection with the MS Powerpoint application via the OLE interface. For the most part this should be reliable but has been known to ‘get confused’, particularly if actions are taken in quick succession (eg. play-stop-play). See the program help tutorials (press F1 or select menu Help > Contents, then Quick Start Tutorials topic) for sample operation and other points to observe when working with PowerPoint.
