On that page try paste some text into any textbox and then lose focus (click somewhere) and then again set focus on textbox. The text disappear! Why is that happening and how to avoid that?

It happens in FF and Opera. In IE 8 not.

Sorry, text should be not pasted. It shoul be dragg-and-dropped onto the textbox.

I tried to attach movie showing how to recreate the issue but movies are not allowed as attachments.

II will try to explain again all steps you must do:

1 Open Firefox 3.6.3

2 go to http://demos.telerik.com/aspnet-ajax/input/examples/common/orderform/defaultcs.aspx

3 select some text i.e. 'The following example'

4 drag text onto Billing Address textbox

5 text is pasted

6 click on the price textbox (or somewhere else)

7 click on the Billing Address textbox again

8 text pasted dissapeared

8a) when you type some text in textbox and then drag-and-drop other text, only drag-and-dropped text dissapear
