I recently ran into a perplexing issue. I had used my standard pre‐loading code in AS3 (using .bytesTotal) in
a media loading project. All of the sudden, IE (of course) stopped loading a value into the .bytesTotal. My loader was
returning NaN. It still completed its ‘loaded’ actions, but wouldn’t track the active loading. Then I tested it
in Chrome & Safari, and it was happening there too! Firefox was fine however. Now I was really confused. This had never been an issue before, but at work we recently moved to a new server solution. So I did a bit of research…
Apparently, I’m not alone. The issue seeming stems from files being served up with GZIP compression
before being sent to the Flash Player. We had the server solution turn off GZIP compression & Voila! It
worked.
Hope this helps someone, like it did me!
