Submitted as a question because some folks may consider this a bug in IE (but not MS obviously because IE8 does the same).  When you upload a new open XML attachment (Office 2007 file extension, docx, ppts, xlsx, etc) the attachment is not recognized properly in IE and it tries to download as a zip file (since the OOXML is actually is a zipped set of XML docs).  This is something that is widely recognized on the Internet ( http://www.google.com/search?hl=en&q=docx+internet+explorer+zip&aq=1&oq=docx+internet ) but is typically resolved by adding the mime extensions at the web server level. 

Are there any plans to add the new mime extensions to the elogd.c source? (Instead of forcing users to use FireFox or Right click, save-as and rename?
