I'm having an issue with the RadTextBox not remaining at the bottom of the text box as you type into it. A few rows after it hits max height (roughly half of max length), it pops up to showing roughly the 2nd line of text and down. Typing a character will briefly pop focus back to the bottom of the text box, but it will return to the 'top' immediately after. RadTextbox is within a cell of a table as well, if that makes a difference.
Text box declaration below for help:
I've only observed this happening in IE8. I also tested in Firefox 11 and had no issues with this there. Telerik controls are Version 2011.3.1115.35.
