@tech@zwo#56619 OK Thanks, found the folder with the FIT's in it, but it would be better if it said, jpg/Fit where it says save, rather than just saying jpg.
I had tried uninstalling it several times from C: and re-installing, and it would be fine, but after a while the sharpen slider would stop having any effect.
Uninstalled from C: and re-installed on E: using the same set up file.
Repeatedly used the sharpen level slider and it now continues to have an effect, so far. Before it would work for a while, and then stop having any effect.
But does that mean I will have to keep it on E: ?
Thanks
