[Plugin: WP-Sentinel] Sentinel Problems with Safari 5.1.x

I’ve been using Sentinel for awhile now, no problems. But hadn’t logged into my site for awhile so don’t know for sure when this issue developed but found myself banned for SQL injection and brute force. And that was just accessing the site page as a user (no login required). Went into myPHP admin, cleared my banned IP, but immediately rebanned whenever I tried to access the site. Tried from multiple IPs, tried from home and now office. Just for the heck of it tried it from Firefox — prior attempts were with Safari (Mac) v5.1.1 and v5.1.4. No problems with Firefox both as a user and logging in as admin. Tried again with Safari, immediately banned. Reset IPs, tried from Firefox, no problem. Have repeated the process five times now to confirm that there is definitely seems to be an issue with Safari and Sentinel 2.0.3.
