Ok, it seems that my english ist not clear enough
Within the Backend, in the Kide-Admin to add/modify/delete Smileys, the Menu is called 'icons' in my joomla-installation (therefore perhaps i used the term 'icon'). Ok ?
Don't know if it's named otherwise in another language...but definitely where to manage the Smilyes.
Ok, with 'New' to create an new Smiley Definition with the needed Code and Image, this works ok to define a new Smiley (or modify a already defined Smiley).
But if you want to store this new (or modified) Smiley, the next screen i always got is the Admin Login Screen and had to re-login, and select Kide-Admin Component again and again.
Checked if the new Smiley is added ist ok, can found it, fine, but the forced logged-off is very unconfortable.
Try add a new Smiley and look if you are also forced logged off.
Hope this was better described
