Re: [Dynapi-Dev] New Animation System

Notes:
- I don't understand why can't you do getImage() before onLoad. Does this effect DynAPI.getImage() in images.js also? It all works fine in Netscape. I will investigate it.
- Label unwrap was removed, it is no longer needed really, I just forgot to take it out of the example file. The text selecting problem is IE specific, I know there is a method that will stop text selecting on a div, this code would be put into Label.setSelectable(). And yes, certainly the border option can be done.
- I quietly rezipped my file after I initially posted my message, I fixed some of the scrolling problems in ViewPort/ScrollBar. Perhaps download the file again and see if it was the same as you downloaded.
- The adding and removing of DynLayers is handled by DynLayer, it would not be a problem specific to my widgets. That problem doesn't affect the Netscape version, so I am almost positive that this is a DynLayer/IE specific bug.
- ImageAnim is definately a good replacement for GifAnim, it has a few features that were not available before like adding several animations, and selectively switching between them at any time, and to play the animations in "alternating" mode where it plays forward/backward/forward... No memory leaks as far as I can tell. You'll see a great application of it in my bumblebee demo when I fix it.
