thanks for your response Kevin, glad to know we're not the only ones having
this problem. The use of FBM42 as extender to FBM41 was advised to us by
Foxboro back in '96 when we setup the first system with CP40's, we didn't
have any problem with 6.5.1 on later CP60's, now all of a sudden someone at
Foxmass seems fit to build in a warning in the new image? they should check
their images more carefully, or did they hire Microsoft engineers ;-) I can
live with the "done"- W59 error - "cancel" method to edit PLB's but it's not
a very "clean" way of saving the block.
Rgds,
Dirk
