This may be due to macro expansion or a bug in CatGraphWindow or both.
File attached.

typed:
hilbert
expected: a loop to be drawn (once) and the turtle to take the paint pot
with him.
got: the loop flashed as it was drawn.
Gets slower like Shlemiel the Painter's algorithm described on
http://www.joelonsoftware.com/articles/fog0000000319.html

hilbert pop // (all on one line)
expected: loop should be drawn
got: nothing happened. Does the type system believe this has no effect?

hilbert // (on two separate lines)
st
expected: turtle to appear on st
got: the curve was drawn again

What version of the product are you using? On what operating system?

Perhaps CatGraphWindow is too eager to repaint when a line is added.
