ifit_fun ( bug ?? )

I have experienced a reproducible error in isis using the ifit_fun 
function. The function enters an infinite loop while prompting for 
input, i.e.

isis> ifit_fun("gauss(1) + poly(1)");
Initializing Gauss[1]:
   Please draw a box to indicate the center, peak and fwhm
click box corners  OR  r)eselect  q)uit
Initializing Polynomial[1]:
   Please click <= 3 points to define the polynomial
   Press 'x' to reposition the last point
   Press 'q' to quit
n=1  x=  1.495443e+01  y=  2.551896e-04
n=2  x=  1.500557e+01  y=  1.398803e-03
n=3  x=  1.505329e+01  y=  4.720818e-04
Initializing Gauss[1]:
   Please draw a box to indicate the center, peak and fwhm
click box corners  OR  r)eselect  q)uit
q
quit

each time a box is selected ( or points for poly ) and it will prompt 
from the beginning again. The only way to exit is with a control C, 
which causes a parameter error.

can anyone else produce this problem?

I am using isis 1.4.9-4 on a Linux x86_64 system

Thanks,
