Hi Mike,
You can find here an illustration of the trouble :
http://www.cipsm.fr/joomla315For this test, I have published :
1/ a connection module on the home page in "Login" position : Connexion button unclickable
2/ a second connection module into "Plg" menu in "Rigth" Pantheon position : Module fully deployed so the module works fine !
In the first case I would like the button to be clickable.
Thanks for you help.
Jean-Luc
