>On Windows Server 2003, I had the Task Manager opened. Suddendly, the header of the window disappeared. I cannot see the options to switch to the list of applications, processes, performance, etc. I closed it and reopened. It is the same thing. Did I click on a setting to do that?


The funny thing that this is documented http://support.microsoft.com/default.aspx?scid=kb;EN-US;193050 (Sergey answered this question before).
