lockfile not getting cleared

[Boaz Bezborodko]

I have a bunch of older programs that don't seem to be clearing the
lockfile when they exit.  The original programmer on these programs
(they may have been written in 3.0 or 4.1) avoided the problems by
running batch files that deleted the lockfile before running.  I would
like to remove these.  But if I do then FP gives an error that someone
is updating the file.  The thing is t even though no one is in there and
none of the files are open.

How can I clean this up?
