... I should add that I've created two instances on the stage for the preloader:
1. A bitmap that fades in as the percentage counts upward, which I converted to a movie clip and called flash_mc.
2. An empty textbox within this movie clip called numbers_txt.
How are the different files located relative to one another (html, preloader, and whatever the preloader loads)?
All the files - rss_feed.html, rss_feed.fla and preloader.fla, plus rss_feed.swf and preloader.swf - are in one folder. I'm only using the one folder for everything, including an mp3 sound file and some .pngs I've imported into the library.
Well, after testing on a remote server there's some good news. The preloader and widget both work fine after uploading to my college's server. I've been testing in Firefox on my local disk and that's been freezing, but things seem to be OK on another network.
Still flummoxes me, but the point of the assignment is to upload the project to a server, not keep it on my local disk ... so I guess I'm happy. But I would like to know if anyone's experienced something similar in Flash, and whether there are some settings I need to tweak to get things working locally.
