Hi,

this is one of the problems that have bugged flash users all the time - you have an attachable sound or attachable MCs, and when you view the movie, the preloader shows up only when the movie is almost completely loaded...
This is due to the fact that such objects get exported to the very first frame, rather than to a frame you choose.
MX now allows at least a choice, but still you cannot specify when these symbols get exported
I have set up an alpha version of a program to help in this situation.
To use it, you have to prepare your movie:
a) make sure that all jumps in the main part are relative (nextframe() etc.) or use framelabels - no gotoandplay(5) or gotoandplay("scene x", 3)
b) make sure that there are no symbols shared between the preloader and the main movie - in particular if you embed a font to show percentages, this font should not be used in the main movie
c) split the movie in two parts; make sure that you remove unused _exported_ library symbols.
d) add a blank frame at the end of the preloader
e) publish two separate swf files (MX: compressed swc files not yet supported), test them independently (the reloader will be too short to view, but the main movie should still work) and upload to http://www.fontimages.org.uk/cgi-bin/swfmerge.cgi
This code is based on F5 swf file format and probably does not cover some tags I never came across, let alone any tags or modifications new to MX. If it does work for your files, please say so - if it does not work, feel free to mail me swf files for checking. I can NOT handle any fla files, nor can I check resulting files that require F6 player or access to a server
