Xml not loading

[jerez_z]

I have a page and its supposed to load some XML. I use the getBytesTotal and getBytesLoaded functions to make a preloader for it. However, sometimes it dosen’t do anything. It sits there at 0 andnever loads. But if I refresh the page several times, then it will suddenly jump to 100 instantly, and work fine. Any ideas?
