I have a couple Image preloaders that work fine on a PC, but when I test on a MAC, the values trace as 0 and the percentage traces a NaN. heres a sample of what I got…

```
loadMovie(Contentxml.childNodes[0].childNodes[0].childNodes[0].attributes.main_image_src,"imageContainer_mc");

```

//and in a loop I have…

infoLoaded = imageContainer\_mc.getBytesLoaded();  
infoTotal = imageContainer\_mc.getBytesTotal();  
percentage = Math.floor(infoLoaded/infoTotal\*100);

I use the values for a big, fancy dial and text preloader, that doesn’t budge on the MAC. The images load fine, just no information on their file size. Any insights or previous experience with this?

Thanks!
