Members having difficulty staying logged in

[Michael R]

Since upgrading to 4.1 I've had a few members complain that they are having difficulty staying logged in. They claim they have to changing their password every time. It lets them in but when they come back it starts all over again.

Also, I am not sure of this is related or not, but I have noticed clicking on the thumbnail link in FireFox asks me to log in but if I just type in the URL I'm logged in.

Thanks!
