There still seems to be one problem. If I clear all cookies and sessions, then login for the first time, I can leave the captcha field blank and it will pass. Subsequent logins work fine, just probs on the first login before any cookies are stored.
This issue only occurs under those particular circumstances. Can you look at it one more time, and if we need to open a ticket (so I can provide you a valid login) let me know.
Thanks again. Attached is my latest code.
