Thanks Adam, but I get the exact same result with the new dll as well.  Any other ideas or info that I can provide to help figure it out?  I get same result with IE or Firefox, so I am guessing it is a serverside issue. 

 

Works with small files, but not larger ones. 

Works on Window Server 2003 32 bit IIS6, but not Windows 7 64bit IIS7.

 

Thanks, Chip
