For some reason i can not get the default text to display more than one word. if there is a space in the call to radprompt only the characters before the space are shown in the textbox. I am using the latest ajax control and the default radprompt.
radprompt('Type:', promptEditToolBarType, 330, 100, null, 'Edit Toolbar Name', 'My Toolbar');
this displays only 'My' in the textbox.
