[comp.sys.mac.hypercard] HC2.1 stack fails under 2.0??

science@oasys.dt.navy.mil (Zimmermann) (06/25/91)

a HyperCard stack which I created under HC2.1 (and System 7.0) fails
and dies spectacularly (actually, it just locks up and won't return
from my XFCN) when run under HC2.0 (don't know about 2.0v2) ... I can
provide the stack, source code for XFCNs, etc., if anybody is very
interested ... any simple/obvious/known reason(s) for this kind of
thing to happen?  ^z (science@oasys.dt.navy.mil)
