gstat GPF !!

[DILPREET SINGH]

Hi,
I downloaded gstat from
http://www.frw.ruu.nl/gstat/bin/gstat-2.1.0.zip

it works fine if I use
c:\gstat>gstat -e map2gif urbnxtnt.001 urbnxtnt.001.gif

but if I say ( which actually is the requirement, else I have to call the
above command again and again)
c:\gstat>gstat -e map2gif anim.gif urbnxtnt.001 urbnxtnt.002

it gives me a GPF, I am using winNT 4. is this a bug or I am doing
something wrong here.

Thanks for your time,

Dilpreet
