When you click to zoom or manual mouse drag or any other option for that matter you are breaking the default movie tour progress. To restart it you must add a button to resume the movie track that it is assigned. It will start again from the interruption point.
You can make many movie tracks and assign these wherever you feel necessary.
This example shows the "default" original Tourweaver "Slideshow" movie track. I have made a copy of this track and set it to be the default, named it omnipix_movie. I have then copied this track again and called it omnipix slideshow and removed the panorama scene (leaving only the still slides from my original movie track) and then lengthened the slide frames display time marginally.
I have made a "Play" button for my skin and assigned the omnipix_movie track to this button. Then another button for the omnipix slideshow movie track (right). It plays only the still shot slideshow. At anytime you can return to the main (now default) omnipix_movie tour track by clicking the "Play" button.
(left) menu slideshow button shows 3rd Party Flash Slideshow via Pop-Up window.
"If" you want to allow people to click next scene and have the tour continue from that point you will need to make multiple movie tracks for each scenario and you will need to use pop-up windows to hide and replace the assigned next/previous button so that the correct button with assigned movie track is present. It can be a bit of mucking around, but this is what is required.
A skip to and continue from option would be nice to have, but currently it doesn't exists. One for the wish list.
