Re: Zone_c.Creating does not recognize allocIVars:

Well, I managed to fix that problem.  I replaced:
 availableGraph=[EZGraph createBegin: self];

with:
 availableGraph=[EZGraph createBegin: [self getZone]];

But, I could still use a bit of explanation as to why it needs this and
why it worked before.
