Whenever I log in, I enter my username and tab down to the password. But when I start entering the password, partway through it jumps back up to the username and puts the rest of the password in front of it.
If I don't notice it, I hit enter and it says invalid password. Now that I do notice it, I delete the extra letters and re-enter the password.
I'm not sure if it's caused by me entering the data before all the graphics have loaded or not, but it is annoying. This only started happening after the newest board upgrades.
