Please excuse us for the inconvenience caused.
I will contact our Web Team and we will research the issue.
Meanwhile here is the reply that I posted to you at the forum thread:
I created two pages with the two DOCTYPE definitions that you use and a RadPanelBar control added to each page. On my side both pages work properly under Internet Explorer.
Could you please find the sample attached and give it a try?
What is different at your side?
Could you please send us working page/pages demonstrating the issue?
Thank you in advance.
Feel free to contact us if you have additional questions.
