y-axis is messed up.

[joseph-hellerstein]

The following model produced a strange looking y-axis.

$Xo -> x1;(k1Xo - k11x1)/(1 + (Z/Ki)^n)
x1 -> x2; k2x1 - k22x2
x2 -> Z; k3x2 - k33Z
Z ->; 0.2Z
G1 = 100
J1: X + Z -> EAP; beta1G1XZ - beta2G1EAP
EAP -> Xs + Z; kk1G1EAP
beta1 = 2E-6; beta2 = 0.01
Xs + Y -> EAPPP; alpha1XsYG1 - alpha2G1EAPPP
EAPPP -> X + Y; kk2G1*EAPPP
alpha1 = 2E-6; alpha2 = 0.01;
kk1 = 0.01; kk2 = 0.01
n = 24; X = 2000; Y = 2000
k1 = 0.2; k11 = 0.05
k2 = 0.34; k22 = 0.02
k3 = 0.34; k33 = 0.03
k4 = 0.44; k44 = 0.04
Xo = 5; Ki = 0.5

I also seems to freeze the app, I have to restart the browser to get effective control back.
