I am having this exact problem (so it would seem) with 12.04.
The Update Manager appears on the launcher, indicating that a number of updates are available. Clicking on the icon in the launcher does nothing.
However, following a time seen elsewhere, right clicking the icon and selecting close does allow me to find and run Update Manager from Dash Home.
