Tag Deletion - Random Crashes or Beachball Freezes (DK 8.5 Mac)

[gz01@iinet]

Maik,

Thank you for the helpful reply. 

Have installed DK 8.6 (pre-release) and deleted the remaining imported tags with no problem. 

Have also enabled writing metadata with ExifTool and my HEIF images’ metadata has now been updated successfully. 

Is there a link to a changelog for the pre-release version?  I did look previously but couldn't find it. 

Thanks again, much appreciated. 

Regards,
Gary
