None of my AsyncTasks get callbacks to onPostExecute
<p>When I have a fresh install of my application, NONE of my <code>AyncTask</code>s seem to work.  It doesn't matter which it is, they all fail with the message "sending message to a dead thread.  "
They're in all sorts of activities doing all sorts of different work, but they all fail.</p>

<p>If I look at the threads in the thread viewer of DDMS, all 5 or so <code>AsynchTask</code> threads appear to be idle and waiting for work.</p>

<p>If I force close the application, and start it back up, they all start working.</p>

<p>They're all started on the UI thread.</p>

<p>Any ideas?  </p>
