I have my root WP directory password protected, so users must login with user name and password to view my WP blog. However, for some reason the login info must be entered twice (I've checked this with several browsers on both Mac and PC). I've tried adding a slash at the end of the URL, and removing the "www" from the URL; no luck.
I found another thread with this problem (http://wordpress.org/support/topic/48807), which suggested creating (in Control Panel) a redirect from 'http://www......' to 'http://...'. I can do redirects with my CP, but not that specific kind (I'm unable to change the www part). I contacted support at my hoster, and they pointed out that if you enter the login info once, and then hit cancel (instead of entering it again) the page starts to load (in Safari it loaded without the CSS). So according to my hoster it was a WP issue, not an issue with htaccess or CP.
If anyone has any thoughts on this, I'd appreciate hearing them. Thanks!
