Test1
Use entry index entryx1
seek Padr("SSB",5)+padr("WEB",10)

Fox20, Fox26 : found() = .T.
VFP6 : found() = .F.

Using either fox2x-
use entry
index on pub+entry for not deleted() to entryx1

then re-issue test1;
Fox20, Fox26 : found() = .T.
VFP6 : found() = .T.

OK, so there's some kind of index corruption that needs to be fixed

The interesting question is Why doesn't it affect old versions of Fox2x?
