icloud.com won't stay logged in

This has only started happening the last couple of weeks - this was never an issue until recently.

In short, icloud.com won't stay logged in for me. I have to enter my info every visit (or at least every time I visit after closing my browser). It's not suppsoed to do that if you check the item under the login screen to remember you.

Anyone know how to get this to stick? Have tried checking cookies, doesn't seem to help.

This is with Google Chrome 18.0.1025.151 beta-m
