Sorry for the late follow-up... I have now finally updated the WFinder 
with these changes as well, so it should be relatively similar to the 
ZFinder.
It's still untested, I hope that I'll notice severe problems within the 
next days when using it, but I'd appreciate if you could have a look at 
it as well since you originally wrote it (+ some analyses which use it).

I'll remove two old UNVALIDATED analyses which I don't feel like porting 
since they are UNVALIDATED anyways.

Cheers,
Frank
