@Matt - Sry I missed this post, pls ignore the inquery via pm)
I'm not quite sure how to change this.
What happens is that there are two possible images for an item: collapsed and expanded.
When you select an item, the image changes (with a fade) and the rectangle animates for the expansion. This results in seeing the expanded image fade at the smaller size and then animate out to the expanded size. The whole effect is a fraction of a second.
When an Expanded caption is not available/empty, could you not just continue using original image.. In the options=>theaterview=>customize file info. It says : If expanded Caption is empty it will reuse the regular Caption.. I assume when expanded caption is empty, you would want to skip it, and continue with original caption, avoiding the fade out effect....
( If that doesn't translate to code: please ignore.
