I've found some unpleasant difference in desktopgrid reaction on mouse and keyboard navigation actions
1. When I navigate via mouse - it's all ok!!
2. When Change cellfocus with keyboard - each time grid automatically changes so, that focused cell becomes left top left visible cell, drastically changing all grid appearance - IT'S VERY ANNOYIN'!
Please, could u change your source code so, that grid always reacts ok!!
