Impossible to modify the duration

[brian]

Are you using the Slideshow Generator?

If so, there is some related discussion about setting the duration here:

Slideshow Generator defaults

Is there a way to set defaults for the Slideshow Generator? I’m getting a pretty good handle on using it for the results I want. Since I have about a dozen more to make before next Wednesday, it would be helpful to have the parameter switches already set to what I will change them up front. Thanks!! —A

If you are not using the Slideshow Generator, can you share a screenshot to show the problem you are describing?
