Possible, I guess.  However, the freechain rebuild was still running when I
closed the app.  If it thought it had fixed any damaged portions of the
freechain and sensed no more, wouldn't it have stopped (exited) the
freechain rebuild?  Or would it continue to run, looking/rebuilding the
entire freechain?  I'm not questioning you, I'm just trying to understand
better what is happening/ triggering this, in the hopes of resolving the
issue.

If the "auto" freechain rebuild is terminated by closing the window, what
are the ramifications?

A) Another freechain rebuild will be triggered shortly, because the original
cause has not been fixed.

B) Any process adding records to this file will possibly take new records
instead of using a previously used, now deleted record.

Lastly, is the Windows version of filePro more prone to freechain rebuilds
than the *unix versions?  Or, because this is a 5.0.13 version, were older
versions more prone to freechain rebuilds?  The main reason for not
upgrading is my app. runs somewhat slower than I'd like currently, and I'm
afraid introduction of the license manager used in the current version will
only slow it further.

I realize these are somewhat risky questions to be asking on an open forum
such as this, but I need to make some progress on several persistent issues.
