Wow, you have been looking a long way back in this forum! 8th december... I have to agree that it would be nice if you could open ppt viewer at a specific location. But what's in it for microsoft? Partly I'm cynical, and partly I sympathise as I program for a living - but I'm pleasantly surprised there's a free viewer at all. I consider it's very reasonable to expect anyone who wants to do more that just view slide shows to pay money to the authors of the software. It's not anti-consumer of ford to expect you to give them money if you want to ride in a car. Someone who makes the presentation is quite capable of printing it to (eg) pdf for other viewing. Or export to flash (allegedly). Yours a-professional-software-writer, Iain. ps... if you want a full screen app in a window... Virtual Machine.
I have now moved to Sweden for love (awwww).
