you have to click on thumbnail to open a file or outside the dialog to cancel.
here is the updated version that will work for save as swf, flv.
I don't know why save as avi did not.
ffmpeg and imagemagick must be installed to work.
I think imagemagick could be avoided with some changes.

edit:
in version 2

you can change the fps
saves xsheet animation file not just ora.
still have saving problems
merging cells,layers problems
