In an attempt to stay current I upgraded to Q1 2009 under my subscription and noticed that all the CSS is not working correctly. I am using IE 7.0.5730.13. Before the uprade it was OK. however it worked best under IE6 where the green lines in the right corner on the first image connected properly. I am not a CSS expert so having to reinvent the skin every time there is a minor upgrade at Telerik is a major drain of time.
I am enclosing a couple of links that show the UI before and after the upgrade. No other changes were made.
