SODIMM, An update will be published this week to reenable the QuickSet functionality of launching Dell Support Center via the Media button.  If you have chosen to receive updates automatically, this update should be applied no later than Monday 9/10.
Following automatic update to Dell Support Center Version: 3.2.6032.47 the middle tray button on my Dell Inspiron 15R (N5110) no longer launches the application. Program can be started via Start > All Programs > Dell Support Center but stutters when using some features and becomes completely unresponsive if I attempt to modify any preferences in the settings menu. I've already tried uninstalling/reinstalling Support Center several times, repairing/uninstalling/reinstalling QuickSet, deleting orphaned folders and removing/changing registry settings as suggested in another post, all without success as the same problems persist. I'm running Windows 7 Pro 64-bit and all other Dell drivers and software are up to date.
