Unfortunately, we are not able to reproduce the problem in our live example
. Could you please check if you are using the latest version of the control (2009.1.527)?
If this is not the case, I think it will be best if you can open a support ticket and send us a simple running project (incl. your custom skin, CSS, images, 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.
Thanks beforehand for your patience and cooperation,
the Telerik team
