I tried to reproduce the problem you describe but to no avail - please find my test page attached. I tested in IE, FF and Safari. Could you please test your code with our latest version - Q1 2009, to see if this would fix the problem? In case the problem persists, please prepare and send me a simple running project, demonstrating your setup, together with detailed information on the steps I need to follow in order to reproduce it. I would additionally need the exact version of the browser you use.
