Frankly, I don't think that's of any importance. Please see a new movie that shows the proper work as you have described it. I still think you are using an older version of the control. Please check again if the application uses 2009.2 826 (or later).
If the problem persists, I think it will be best if you can open a support ticket and send us a simple running project (incl. CSS, images, skins, DB backup if needed and so on) demonstrating the problem (and step-by-step instructions on doing so). In that way we can reproduce and pinpoint the problems you're facing on our side, understand the logic of your application and provide a solution.
