I happened to notice that the Post Work Manager is not working in PP2014.  Doubled checked if the same script was functional under PP2012 and, indeed, it is working fine.  I opened a ticket with SM to investigate the problem.  The attached screencap displays the script error.  PP2014 is installed into WinXP Pro 32 bits; SR2 is recently installed.  Unknown whether the script was working before SR2.
