Something in the system-configuration that dopus doesn't like, or weird version of a library...
you would need Dopus.library if ya don't have it....
I think..
Heh, havn't fiddled with libraries, system-configurations since I used a real amiga back in the early 90's
.. so donno....
if snoopdos works under a normal wb 3.1, why don't you then run snoopdos and then dopus to see what made dopus crash?
