Bug when login with Google Chrome

Hi,

I am using WP 3.6.1 and UAM 1.2.4.3 and I have a bug when I try to login with Chrome. After submit the login form, I am redirected to the page, but UAM displays again the login form and not the page content. At this step, if I reload the page (without reposting the form), the protected content will appear.
I have only this bug on Google Chrome. This works fine in Safari, Opera, FFX.
Any Idea ?

Thanks in advance,
Xavier – tix02
