1) You can now set your window mode for each Showtime slideshow.
using WMode Opaque will cause the flash to appear on the correct Z-index, so that it does not hide menus or other objects, whereas WMode Transparent is always on the top layer. For me the best experience is leave it on "Opaque".
2) New helpfile... check it out
3) TinyMCE WYSIWYG intigration, Goto your TinyMCE WYSIWYG options, vink on showtime_picker and dont forget to add [showtime_picker,] to your Profiles toolbars.
