How about posting a URL? I'd be happy to try it out for you.

Also note that IE is notorious for "lying" to the user about progress - on page 
loads for example, their progress bar often moves even after your net connection 
has gone down. Not sure if they're doing that on the file download progress bar, 
but it's something to be aware of.
