And last curious thing : the fact to change the Shortcut for a version ("appdata" for Beta V4 - not "appdata" for the V 3)
changes also the Shortcut for the other version of Moi! A true ghost story! :)
I suppose that's explaning my previous "White window" !

So must Copy Past the good path from somewhere if i want use Elephant on an another version of Moi!
(and of course a little trouble with an error "\u8203" during the Copy/Past path for spice things! :)
(seems CTRL C - CTRL V doesn't like to past a selected text from Website - must use the "contextual menu" Right Click !
