"Kill Function Running On This File"

[Boaz Bezborodko]

I'm trying to go into the program on a particular file, but I get this
error when entering "Define Processing"

filePro Directory - Kill Function Running On This File

File not available.
Somebody else is modifying the file;  try again later.

I never saw this on 4.8.  Is there something in 5.6 that keeps you from
editing programs when someone is in the data?  (They have the data file
open, but not any of the programs.)

I'm running FP on windows from a Samba server.
