[Dx4win] Resolution of F8 issue

[Garry Shapiro]

Here is what appears to have "cured" the problem:

I re-opened the current log file that was exhibiting the problem and found
that the problem was still present.

I closed and reopened DX4WIN. The file now sorts normally!

There appears to have been a partial corruption that did not disturb most
normal program operation, but which reset  when the application was cycled.
I suppose that to programmer types that is an obvious thing to try first
before asking for help, but it was non-obvious to me. I would still like to
understand what happened.
