Once you get the correct path, you can enjoy css dropdowns in IE 6. But this setup doesn’t work on all web servers. Some server do not have a mime type set for .htc file, and, as a result, your csshover.htc file will not work. You can easily fix this if your host allows .htaccess files. Insert the following code into your .htaccess file and upload it to your server. That should fix the problem:
AddType text/x-component .htc
If you don’t have a .htaccess file, create a text file and name it .htaccess and then insert that code above.
