Add a new file called others.browser to the app_browser folder. This can also fix the asp.net Menu control under chrome. The file content as below:
<browsers>
<browser id="Safari3" parentID="Safari1Plus">
<identification>
<userAgent match="Safari/\d+\.\d+" />
</identification>
<capture>
<userAgent match="Version/(?'version'\d+\.\d+)" />
</capture>
<capabilities>
<capability name="browser" value="Safari3" />
<capability name="version" value="${version}" />
</capabilities>
<controlAdapters>
<adapter controlType="System.Web.UI.WebControls.Menu"
adapterType="" />
</controlAdapters>
</browser>
<browser id="GoogleChrome" parentID="Safari3">
<identification>
<userAgent match="Chrome/(?'version'\d+\.\d+)" />
</identification>
<capabilities>
<capability name="browser" value="Googlebot" />
<capability name="supportsMaintainScrollPositionOnPostback" value="true" />
</capabilities>
</browser>
</browsers>
