[Skimmertalk] Trying to optimize CPU while skimming - More FT8 questions

[Dave Pascoe]

I have "None" set on the Save menu on all of mine and they still save 10's
of GB's worth of WAV files in that ...save directory. I did some research
on this and it appears to be a bug that has been reported before. The
WSJT-X team doesn't seem to have an external-facing bug tracker but I did
some searches on their mailing list archive and it seems there is never a
good answer as to why this seems broken. The only clue seems to be one of
the developers (or at least he seemed to be) shrugging it off as something
that might be happening if WSJT-X exits abnormally. It can't just be that,
if that is true. I have far too many of those files...in fact it consumed
all the drive space on one of my systems because I wasn't paying attention.
I only sort of remembered about the WAV files when I went searching for the
greedy consumer of drive space.

I can't find a place to report this bug so I guess I will email K1JT and
see what he says. But I do believe it is a bug.
