Thanks for all the input guys. I understand the complexities of programming, I worked at a large bank as an IT technical specialist for the past 20years but have given it up to do photography full time I perhaps shouldn't have called the manual control 'basic' functionality, I meant 'original' functionality - I need this expressly because I use PTE for giving lectures so I use a remote pointer to move the slides on manually. Introducing pan, zoom and rotation should have no bearing on the complexity of this as KSF implies, I merely want to tell PTE when to change a slide. Any motion built in should just happen as planned. I've only just really started to do AV talks having bought some Bose speakers, but I have to confess that I am using Proshow Producer to do the intro with all it's motion effects and multi-slide layering etc, this then kicks off a PTE main body of the talk and PTE in turn kicks off a big AV finale using PP again. The only glitch is when PP kicks off PTE as there's a brief flash of the desktop. However, when PTE kicks of PP it is seamless I just figured that rather than simply have the static nature of the slides in the main part of the talk, I could throw in a few slides that zoomed and panned etc. Lin - any chance you can link me to the Proshow forum? I have some complaints of my own I'd like to throw in. Nick - send me a mail re studio flash at any time. I'm a Bowens man FWIW. John
