TOPIC:

A scroll bar appears when using the Advanced Image page with an image set to Auto and adding a Narration element to it. It should recognize the added controls and scale accordingly, but it doesn't, and the scroll bar is unsightly and unnecessary if all the content fits on one page.
This issue makes adding Narration to this page type (and probably others as well) difficult, basically every image needs to be scaled manually to the correct dimensions.

Hi
try upgrading to Xerte 3.11 which is now 3.11.5.
The 3.11 release includes improvements to a number of page types including Advanced image. You will no longer see an Auto option and instead you will see small, medium, large, fixed and full screen. Vertical scrollbars should not occur even with narration in place.

It works fine in the new version, thanks!
