This problem used to happen in the 1.0 AJAX/2.0 runtime version but was fixed.
However the 3.5 AJAX version has this bug.
If you use the latest mojoPortal release or mojoportal built from svn using
MonoDevelop, this bug manifests everywhere we use an UpdatePanel.
One example is when adding categories to a blog post the category is added but
the page does not refresh.
Stacktrace is as follows:
