Hello,

I wasn't able to reproduce the described issue and you are the first to report it.

What I can suggest at this point is that you try the following:
- clear the browser cache and the ASP cache;
- disable the plugins in the problematic browser;
- check whether the issue is encountered with the latest version of RadControls for ASP .NET AJAX.
 
If you continue to experience the issue, please try to reproduce it on some of our online demos.
If no avail could you please isolate it and send us a simple, fully runnable project, so that we will be able to examine it locally?

I am looking forward to receive your reply.

Regards,
