Please restart EmEditor and try Export again.
Yes, that was just what I did. I checked to ensure no process of EmEditor or Emedtray remained.
One more thing I can report is that, in eeCommon.ini, these items also lost their Size data:
*-Size values exist only in INI files, and not necessary in the Registry.
I don’t know why you cannot import some other values to the Registry. I will try to reproduce your issue, and will let you know. Thanks!
