When unload contextmenu, it maybe change the body's class

when a contextmenu’s parent is body, and unload the contextmenu, it will change the body’s class, because in dhtmlXMenuObject.prototype.unload will call this.base.className = “”, this line code will change body’s classname, this maybe affect all element in the body.
thanks!

The unload() method calling won’t clear the body class as the (this.cont != null) condition is false.
