ok .. found a solution for chrome, egde, safari, opera ...
i changed to https://greensock.com/tweenmax
and i animate my things with :
Panels:
UniSession.AddJS('TweenMax.to('+UniContainerpanel.JSName+'_id,0.4,{left:'+inttostr(x)+'});');
Forms:
UniSession.AddJS('TweenMax.to('+self.WebForm.JSName+'_id,1,{autoAlpha:0});');
Works fine :-)
