Web Forms :: Vs 2010 + Asp:menu VS Safari?

I've a project written with visual studio 2008 + asp.net 3.5 that renders perfecly also on safari browser.

I converted project to VS 2010 (without upgrading FW to 4.0, but manteining 3.5).

Well, locally using safari it renders perfectly, but on server (on server is installed only FW 3.5) it does not render correctly.

I've to said that in BrowserFile.broser i've:

<browsers>
<browser id="NewBrowser" parentID="Mozilla">
<identification>
<userAgent match="Unique User Agent Regular Expression" />
</identification>
<capture>
<userAgent match="NewBrowser (?'version'd+.d+)" />
</capture>
<capabilities>
<capability name="browser" value="My New Browser" />
<capability name="version" value="${version}" />
</capabilities>
</browser>
<browser refID="Mozilla">
<capabilities>
<capability name="xml" value="true" />
</capabilities>
</browser>
<browser refID="safari1plus">
<controlAdapters>
<adapter controlType="System.Web.UI.WebControls.Menu" adapterType="" />
</controlAdapters>
</browser>
</browsers>

i've also tried to delete safari section, but on server is still not working.
