each export has the background in it.
I have looked into the publish setting for gif but no option there, or in the background colour setting in the main design window has any Alpha or Transparency setting.
Hi, yup that transparent checbox is checked. still showing background when exporting animated gif
Thought that issue went away. The only workaround I found was exporting a PNG sequence with transparency, importing it all back into a better animated GIF exporter like Fireworks as an image sequence and exporting it from there again. It will give you the best quality, control over the timeline, looping and various per-frame AGIF functionality.
But yes, it's a multi-step headache.
