Thanks for the detailed explanation. Here's an idea: What about changing onFocus to this:
Does that solve the issue?Code:onFocus : function(){
if(!Ext.isOpera){ // don't touch in Opera
this.el.addClass(this.focusClass);
}
if(!this.hasFocus){
this.hasFocus = true;
this.startValue = this.getValue();
this.fireEvent("focus", this);
}
}
