Keep getting logged out

A new issue I just noticed today: I get logged out as soon as I navigate to a new forum.
Even though I set the 'log me in whenever I visit' bit, I have to re-enter my username and password.

Have you seen the box that tells the software to keep you logged in forever, or however the wording goes? It starts with a time figure (like 120 minutes or such), but I like the "forever" feature myself. I can spend hours here jumping from one thread to another!

Was having that issue; traced it to cookies being too restricted by the browser (chrome) I'm using.
