Ruslan (and others),

I'm using V4RB 1.9.7 --- I'll give the beta a try and see if that fixes it.   
I'll post later and let you know how that went.   

Yes, Carbonlib 1.6 is "advertised" as compatible with OS 8.6.

I'm not using PPC because of a problem with another RB plug-in --- I must 
compile in carbon to work around some cosmetic problems that occurr with that 
plug-in under PPC.    However, if I can't V4RB to work under carbon, my customers 
are just going to have to accept some cosmetic problems :-( .   I can't work 
around Valentina.

No one has come forward and said they are using V4RB successfully in the same 
configuration (OS 8.6, Carbonlib 1.6), so perhaps I am the only person in the 
World doing this.    Ruslan, I'm not sure it's worth your time worrying about 
it.   Potential V4RB users still might need to know up-front that Carbonlib 
1.6 + OS 8.6 "kills" V4RB (but Carbonlib 1.6 + OS 9.2.2 works fine with V4RB).

It's just speculation on my part, but I think based on the info Charles 
shared, the "core" problem has something to do with how folderitems are 
"communicated" between V4RB and Carbonlib and the OS.   The app crashes at "bool = 
db.Open(f) ", whereas the same line in PPC under 8.6 works fine.
