Terry,

open your NE555 schematic symbol in the library editor, click on the "Edit 
component properties" icon on the toolbar, and de-select the checkbox marked 
"Power symbol".  The popup tooltip you get if you hover the mouse over this 
option explains what it does.  For a real component, you don't want this 
selected!

I also noticed that you defined all the pins to be "passive".  This isn't a 
brilliant idea.  If you define them to be what they really are, then the 
electrical rules check will tell you if you've done something silly in the 
schematic like connect 2 outputs together, or have an input that isn't driven 
from an output etc.

The only thing to watch out for is that when you've defined the Vcc pin to be a 
"power" pin, it needs to be driven from a power source.  On this simple design, 
the power is coming in from the connector, which of course should have all pins 
as "passive".  You therefore need to add a "pwr_flag" from the power ports list 
to tell Kicad that it's ok.

Nick.
