tabbar Invalid argument...IE 8 dhtmlx v.3.0

Hi!

i’am using the dhtmlx tabbar v.3.0 (free edition)

and in IE 8 i see this error “Invalid argument” at line 771 of dhtmlxtabbar.js

code of dhtmlxtabbar.js
setSize : function (a, b) {
this.entBox.style.width = a + “px”; //LINE 711
this.entBox.style.height = b + “px”;
this._setSizes()
},

firefox/chrome is ok, only IE 8…

What can i do? Thx
