If viewing a short video, or closing WMP on longer video, either from a local
hard drive or from a web site, the WMP window will close, but using task
manager, the process "wmplayer" continues to run for about 10 seconds. This
happens on both my home system and my work system, which have significantly
different hardware and drivers.
Until "wmplayer" process terminates on it's own, or until I terminate it via
task manager's end process, I can't run WMP.
