Created Unassigned: Combined scripts are not cached [27531]

Hello,
I just tried to set up combined scripts with the last version of ACT and it seems that scripts are never cached.

page.aspx
```
<act:ToolkitScriptManager runat="server" ID="ScriptManager1">
</act:ToolkitScriptManager>
```

AjaxControlToolkit.config
```
<ajaxControlToolkit>
<controlBundles>
<controlBundle>
<control name="ModalPopupExtender" />
</controlBundle>
</controlBundles>
</ajaxControlToolkit>
```
web.config - handlers added

See attached screen. Everytime page is reloaded, all scripts are loaded from cache, except ACT.
Any solution for this?
