The code i want to run is:

<telerik:RadRichTextBox x:Name="mytextArea1" Width="20"/>


The version i have is the last one for silverlight (Q2 2010 i think).

Thanks

Hi David Petronzio,

Thank you for this bug report. I will add this issue in our to-do list for SP1.
As a workaround, avoid setting RadRichTextBox's Width under 27, or if this is required, set the PageLayout property of the RadDocument to Paged.

Best wishes,
Boby
