navychief, if the issue is 100% reproducible, could you provide us with a dump file of prl_cc.exe process? This will help us to investigate.
To create the dump (before you are going to shutdown) open Task Manager, go to the Processes tab, find prl_cc.exe there, right-click->Create Dump File. Then zip the file and attach to this thread. Thank you.
Also please generate a problem report:
Initiate shutdown, then while prl_cc is hanging, select from VM menu (if in Window mode) Help->Report a Problem, or from II menu (if in Coherence mode) Alt+Click->Report a Problem. Then post the report number here.
