Thanks for resetting my password Suzanne. I discovered it was actually Firefox auto-filling the form and starting my name with a capital letter when my login doesn't have one. I fixed the problem by going into Preferences - Security - saved passwords, and deleting the one for here and the blog. Then I typed my username and password in again and saved them (for those who are concerned about my security, no-one uses my computer but me, and I log out every. single. time. I'm not actually using it. Comes from working in the IT department...)
Hope this helps someone else!
