How much of a difference is "slightly"?
My first instinct would be that there are slightly different versions of fonts installed, but I have no idea. Or perhaps one of them has been updated to 10.0.2 and the other not? Just grasping for ideas here.
The way to check would be to turn on the generate size report in the Flash publish settings and compare the reports from the two machines.
Are thay have a same publish settings? the differences may come from fonts and sounds compresing
The difference was 3k but in banners, that's enormous. I feel silly for never thinking of looking at the size report... actually I had looked at it... but I was overlooking the font size since it was the same font. Although it was the same font, it was from a different font publisher and was, in fact, larger. It's always the obvious things that gets overlooked, isn't it? LOL
Thanks Rothrock for pointing out that snake that was about to bite.
Of course the publish settings were the same. I did say that all I did was open the file and publish.
Note that publish settings is per program not per fla file.
Pulled this straight from Flash Help:
"If you change publish settings, Flash saves the changes with the document."
