I can reproduce this under regular (NON-student) version 5.1.1 under 
Windows XP Professional (SP2), except that:

   (a) I see the entire "Command Completion" in the title bar of the 
pop-up window;

   (b) the second pop-up window seems to be the same size as the 
original one.

That both windows disappear after you select the command is no surprise,
