Login unrecognized to allow comment Answered

Good day!

I wanted to leave a comment for one of the instructables, but when I place my cursor in the comment field, the login screen pops up. I entered my username and password which appears to work, as the page reloads, but when I scroll back down to the comment box and click to place my cursor, the same action occurs (the login popup appears). Thinking it may have been an incorrect password, I requested a password reset, followed instructions and was successful in changing the password. Back to the 'ible and lo and behold the same action occurs. I tried Safari and FireFox (current version) on Mac (10.9.1) to no avail.

Help!
