Hi AG, the auto movement you described is auto pan and zoom. This is applied by default but there is a way to turn it off. Load your project then in the main window select the orange spanner icon just above the storyboard panel 'slideshow options'. From here un-tick the 'enable pan/zoom on slideshow' option. This then removes pan/zoom on all your slides which means they remain static or still. This option applies to the current slideshow, so if you have multiple slideshows then you have to select it again for them. Also when you create new slideshows, there will be an option to have pan and zoon automatically on or off.
Hi AG, yes there is a way, enable 'pan/zoom on slideshow' as described before, such that all the slides have the pan and zoom effect. Then left click on a slide which you wish to turn off pan and zoom. This then brings up the normal slide options tabs on the top/left. Select 'pan & zoom' then tick 'Turn off pan/zoom for this slide'. This then turns off pan zoom for that slide.
