I took a look from my Mac and I found that if I manually visited the site and clicked the link to open the login form that I could fill. I could also fill without the field being visible i.e. I filled, then clicked the Login link and found the two fields were filled but what won't work is open and fill. No matter what I've tried you will need to click the Login link to bring the form up to allow it to submit. If you're a Firefox or Chrome user I believe most of this should apply equally to 1Password for Windows too but I'm not in my normal situation to confirm this as being definitely true (as is my preference). Does this match what you're seeing?
