Assuming, dangerous I know, that you can sign in usually with no problem and make no changes before you have the problem you may be on a slow or finicky internet service. My experience is that Bike Forums is the slowest to load and most different web site I visit. It is the only site I get errors associated with loading. Sometimes a notice the internet service timed out waiting for BikeForums. Other times just a Not Responding.

On this web site if you don't want to continually reenter your ID and password you do need to have the remember me box checked.

At least this has been my experience with no difference between browsers, which is as it should be since the same basic software is used by many wib sites.
