    Hi
    We're fixed this bug in the next 8.2 update. Currently you can use the following workaround. Please add a new controller into the Module.Win:

    C#
        public class MyLookupPropertyEditorDropDownWindowSizeController : LookupPropertyEditorDropDownWindowSizeController {  
        public override void UpdateModel(DevExpress.ExpressApp.Dictionary dictionary) {  
//            base.UpdateModel(dictionary);  
        }  
    }

    Thanks
    Mike V.
