The thought crossed my mind as well, but it seems way to drastic for MS hehe. I think it might be something to do with how IIS handles file extensions and assosiations, though I'm not sure what...

I'm starting to think Microsoft is rely Evil.
As you might know civproject.net is run on Velusion's Windows Server, using Microsoft IIS as webserver. My server however, is running Linux with Appache as web server.
At my server I have no problems to host any files, but some files just does not work when I have uploaded them to civproject.net.
PDF files and ZIP files works just fine, but ODT files just dont work.
Try this link for example. I promise, the file is there, but IIS will just not show it to you. However, if I take exactly the same file, but rename it to .doc it works. Of couse, it still is an ODT file, and will open just fine in OpenOffice (but will not work in Microsoft Word). It also works if I call it .zip, and this time it's actually correct (an ODT file is a ZIP file with a predefined set of XML and PNG files inside), but still not realy usefull (I don't want to open it in Ark, I want OpenOffice or Koffice), so I must name it .odt, but then I'll just get "HTTP Error 404 - File or directory not found."
Considering that Microsoft does not want you to use ODT (they'd prefer you pay for Windows and Office to use .doc or .docx) I'm starting to think this might be deliberate somehow...
