login box keep poping up

Hello
I have 2 websites using the same easysocial.

testing website : test.rasf.fr
main website : rasf.fr

If you go on both you will see that the rasf.fr website keep on showing your popup login box where as on the test.rasf.fr it doen't do it so often.

Can you help me out with that problem as my main website is also for non easysocial user and I do not want to bother them with a popup login box.

thanks
MArco
