Software Updater checks for new updates daily, and when it has found updates, it displays an icon on the launcher. Clicking on the launcher should open Software Updater, whereupon the user is prompted to select and install updates.
However, after I upgraded to 14.10, when software updater's icon appers in the launcher, it is unresponsive to clicking. While the icon is still there, attempting to launch a fresh copy of Software Updater from the Dash will not work, as there is an instance of update-manager already running (it's actually sleeping). It is only when I manually quit the update-manager (right clicking on the icon and then click "Quit" will do) that I can relaunch Software Updater.
Curiously, after relaunching Software Updater in this case, it will forget about its previous window size, and default to the tiny version instead.
This problem happens every time for me, so I'm not sure of the exact circumstances under which it's replicable.
