I wasn't really trying to provide a fix, simply describing what I encountered.
Machine Specs - well, since yours is likely newer than mine, and mine worked anyway, therefore it seems likely we can rule out the idea of a sub-standard machine.
Single screen - because my laptop was not connected to anything else (like a projector), I wondered aloud whether the problem that I experienced was simply a case of PPT2007
requiring a dual-monitor environment, at least for its first run from within Zionworx.
Rebooting - always worth a go ...although I'm surprised it wasn't required after installing Office 2007 (BTW - you wrote 'Works 2007' - is that correct, or did you mean Office? I wasn't aware that Powerpoint shipped with MS Works).
I'd be interested to hear if anyone else...
- has encountered this problem too?
- knows why it has happened?
- knows how to prevent it?
Hope you get it sorted soon
