Exporting a Movie as a GIF

okay so i got this pretty little picture…

and i motioned tweened a little animating fly, buzzing around happily

now it worsk perfecto when i export as a SWF, everything is great and fine

but I want to publish the file as an Animated GIF, but when i do, my BG picture gets REALLY grainy

it just looks terrible compared to the old picture.

how can i PREVENT this? its almost like Flash doesn’t want to add any more colors to the GIF, :frowning:
