HtmlEditorExtender throws an exception when trying to change background or foreground colors. See how it [looks like](http://screencast.com/t/caR0xaAWzE17).
It can throw two different type of errors. The first one:
```
Uncaught IndexSizeError: Failed to execute 'getRangeAt' on 'Selection': 0 is not a valid index.
```
The second one:
```
Uncaught Sys.InvalidOperationException: Sys.InvalidOperationException: 'unselectable' is not a property or an existing field.
```
See attached screenshots.
Comments: Hi, This issue is already fixed and this fix will be available in the next release of the AJAX Control Toolkit (v15.1.3). Thank you for sharing your experience! Best regards, Fadil
