Ack...I wish I had better news.
This is what happens: We log in, and then go to another part of the site. Then maybe we close our browser and later on return and are forced to log in again. It happens 10 times a day.
This is what we want to happen: Log in once and never again do I login.
This is what probably will happen for our own security: We'll login once per 24 hour period.
I have no date as to when this will be fixed but I did want to apologize that this is happening and let you all know that we identify with you. This issue is annoying and it's on the list.
