I got the solution, just need to check for NSStatusBarWindow className as
follows:
if([awindow isVisible] && ![aWindow aboutWin] && ![aWindow loginWindow] &&
![[aWindow className] isEqual:@"NSStatusBarWindow"])
Thanks.

In order to display anything, it needs to be placed in a window. Your code
above is correct in that it doesn't send -close to any status bar items, but it
*does* send -close to the invisible window that constrains them. That's why
they disappear.
You'll probably want to do some more careful checking of the windows prior to
sending them -close. Perhaps check the class of their window controller or
their delegate.
