That's a surprise. Can you try reproducing it on dropthings.omaralzabir.com?

If you go to the second tab, there are buttons that produce server side 
postback.

Yes, I went to http://dropthings.omaralzabir.com  and clicked on the second 
tab.  Then I clicked on the buttons which produce server side postbacks.  No 
issues.

Is there some code from one of these widgets which I need to add to avoid the 
issues reported at the top of this message thread?

I need to be more specific.  I am trying to add an asp:Button click event from 
the Header.ascx.  This is were I am experiencing the following errors.

'DropthingsUI' is undefined.  MyFramework.js is not loaded.
Widgets no longer function after closing JavaScript popup error.

What do I need to add to the Header.ascx in order to not experience these 
JavaScript errors?

Upon further testing... I added a test asp:Button in the Default.aspx.  
Clicking this button also causes the following errors.

'DropthingsUI' is undefined.  MyFramework.js is not loaded.

Widgets no longer function after closing JavaScript popup error.

asp:Button postback test works from inside test widget .ascx control.  However, 
button postback from OUTSIDE widget .ascx control throws JavaScript errors.  
'DropthingsUI' is undefined.  MyFramework.js is not loaded.

Help please?

i was getting this weird error. the found that scriptmanager injecting 
javascripts incorrectly due to virtual directory. updated as following and now 
works fine.

<asp:ScriptManager ID="ScriptManager1" runat="server" 
EnablePartialRendering="true" ScriptMode="Release">
    <Services>
        <asp:ServiceReference InlineScript="false" Path="~/API/Proxy.svc/ajax" />

        <asp:ServiceReference InlineScript="false" Path="~/API/Page.svc/ajax" />
    </Services>
    <Scripts>

Scratch my previous comment.. I reported a separate issue for that (which on 
closer inspection, appears to be unrelated). However, to chime in on this one, 
I do not think the proper solution is to include external .js files. Shouldn't 
cross-site scripting be avoided, when possible? This seems like a workaround 
for whatever virtual directory issue was being seen, rather than a solution. 
Keeping jQuery files in the Scripts folder maintains the version that is known 
to be compatible (should a newer version not be backwards compatible in some 
respect).

Not sure if this is the same problem.

Put this script in a widget to produce 'DropthingsUI' is undefined error

<script type="text/jscript">
function timedRefresh(timeoutPeriod) { 
setTimeout("__doPostBack('WidgetBodyUpdatePanel', '');", 10000);} 
timedRefresh();
</script>
