NIS 2010 Icon Appears on Taskbar After Changing Docking State

I have my laptop set (in bios) to "warm" docking; i.e., when I issue the undock command, it changes its docked/undocked status and then suspends.  Since the NIS 2010 17.5 update, when I resume, NIS 2010 appears on the taskbar as if I had opened the application window and then chosen the "minimize" setting.  It does the same thing when I suspend while undocked and then resume after re-docking.

This doesn't happen when I simply suspend and resume without changing the docking state.
