Preloader?

So here’s something I’ve just discovered. All my loadmovies have a preloader on them.

When I test the movie from flash the SWF preloader reads

“% of 42K loaded.”

When I upload the SWF’s to my server, all the SWF’s read

“% of 132K loaded.”

They are not all 132K, why is this happening? They all show the appropriate K in the SWF but they don’t on the server.

Any thoughts?

Thanks
