The mailing list for listmasters using Sympa

[address@concealed]

Hi, I've installed sympa version 4.1.2.

If I click login sympa open correctly a popup, but when I insert any valid 
mail and password it returns in the popup "You are already logged in as ...".
It dosn't close the popup but if I use wwsympa it seems to work perfectly.

Any idea?
