Hello, we have already found the problem. You put rewrite rule on wrong place in .htaccess file. You put it after final rewrite "RewriteRule .* index.php [L]" so webdav rule was never fired. I have tried with Windows 7 in MS 2010 and Windows XP in MS 2003. For me it works. Please use CTRL+F5 or cleanup browser cache because we have updated JAVA aplet on your site.

Hello,

Yes, this works now. I tested on two machines and two browsers. Important to have the latest Java enabled. Perhaps the install instructions were not clear to us.
