'Ken Burns' transition effect in features

[grt 0]

Hi all, I desperately want to achieve a 'Ken Burns' transition effect between slides in the features set-up, but cannot do it. Normally, on slide show applications that don't have the feature installed, it is possible to achieve the effect by making the transition time really long and the slide duration really short, but in this case it doesn't work. Does anyone have any ideas on how I can achieve it? Many thanks, Glyn
