It looks like it's not a question of running DrRacket for a while, but

about DrRacket, but about showing a window containing a `tab-panel%`

Do you have a Racket installation on a different machine that you can
check? Whatever the problem is, my guess is that it's specific to OS X
(but that's just a guess).
Does it matter
I just wrote a simple 2htdp/universe program that animates a moving green
