Any problems with v18 tools?

You can ask about those kinds of problems in the forums or make feature requests and log bugs at www.adobe.com/go/wish.

With v18, we changed the architecture of slideshow overlays to allow nested overlays. In doing so, we inadvertently changed the behavior of slideshows created with previous tools. For example, behaviors such as the timing of auto-playing slideshows and stopping at the last image no longer worked properly. We think we fixed all of these "regressive bugs," but we want to make sure.
