  1. thebouv,

    I’ve never tried a FileSystemTree control, but if it looks like a bug can you please file a bug (and include a simple test case, if possible) at http://bugs.adobe.com/flex/ if it isn’t already in the bugbase. (Please file against the “Flex SDK” project and “AIR: File System Tree” Component.)

    Thanks,
    Peter

  2. How do you respond to the end of that effect though? some type of effect_end event or something. I can’t seem to figure that out..
