I'm changing some text in a .fla file I received from a client. Together with the .fla files, I've also received the original .swf files. However, when I change the text & export new .swf's, they're substantially bigger (in file size) than the originals. An original .swf of 29 kb will - after translation - be 37 kb.

This even happens with files that have no .jpeg files.

If I export them to Flash Player 6, they're a bit smaller - since some of the newer fill functions aren't supported in FP6, they're ignored by the compiler.

Any idea what I can do?
