Please run the Setup page from /Setup/Default.aspx and see if the configuration 
is correct.

That was the first thing tried, no problems detected.

Can you show me the exact error message?

One thing, your error message says DropThings, but the class name is 
Dropthings. No capital T.

Can you please check if this script block is appearing before the <script> tag 
that loads MyFramework.js?

I looked at the page source and the __doPostBack is before the <script> tag to 
load myframework.js, same as all the other __doPostBack calls.

I've attached the TestWidget files.

Most likely the timer is firing before the MyFramework.js gets loaded and thus 
it fails. 

I suggest you put a check to ensure DropthingsUI is defined before calling 
__doPostBack.

also there's no ref to DropthingsUI in the script. I am surprised it is 
happening because of this block of script. Maybe it is happening for something 
else?

I've simplified the demo by creating a blank widget and adding a single control:

<input type="button" value="Display timed alertbox!" 
onclick="__doPostBack(this.controlID, '')" />

The post back etc all works fine, TestWidget.Page_Load is called as expected, 
the undefined error happens somewhere when the page is being redisplayed. I 
can't see where DropthingUI becomes undefined during the process. DropthingsUI 
doesn't become undefined when 'Add Stuff', widget 'Edit' and the like are used.
