if I configure a HTML5-portal connection of type "RDP" to a Win 2008 terminal server (didn´t try with other RDP servers), and use my iPad (IOS 4) to connect, die RDP session establishes pretty nicely - the whole screen is transferred. However I cannot log in to the RDP server becaus when I focus the cursor into the "username" or "password" input fields no keyboard interaction comes up, so I cannot log in. Seems the iPad doesn´t recognize that the cursor is in a text input field now.
Connection from a normal webbrowser (FF, IE) works perfectly.
