The transition settings are applied only when moving forward or backward between two consecutive frames.
In non-linear situations (using the frame list, Home/End keys, hyperlinks), these settings are not always relevant and may produce unexpected results. A default transition of 0.5 sec is used. It is not customizable in the current version of Sozi.
As far as I can tell, there is no work around for your problem.
A future version of Sozi could include the following features:
- Make the default transition customizable.
- Add an option to the transition settings, allowing to use these settings even in non-linear transitions.
- Allow to add transition settings to hyperlinks. There is already a feature request for this
