Upload Progress always 0% until it's 100%

Tue May 15 17:47:11 EDT 2007

Hi Greg, yes, because the start action in the files controller has no  
layout, the mup.js javascript is not being included. Without this,  
the progress bar isn't displayed at all, even at 0%. So you have to  
either remove :layout => :none from the start action in controllers/ 
files.rb, or remove the <% throw_content :header %><% end %> wrapper  
around the CSS and javascript include in views/files/start.herb.

Cheers,
Mike
