Thank you for contacting us.
We were able to reproduce the problem. It occurs with the Q1 2010 beta version of the controls, you are right. However, the problem is only for the Office themes. We will do our best to fix the issue for the official release. Meanwhile, you can use one of our other themes.
Your Telerik points have been updated for your involvement.
If you have any other questions concerning our controls please feel free to contact us again.
All the best,
the Telerik team
