HI All--

For Isodat 2.0, you have "Dynamic Background".  But you really have to 
play around with it to make sure it's not being funky.  It will pick 
points before and after a peak as baseline points, then draw a (sloping) 
line between them for the baseline. You have to hit the "Dy" button on 
the screen to see the dynamic background. 

take care

gerry
