I've been attempting to import a file into the Custom Property Editor to populate several Nodes fields. While the import completes without any error messages, I never see the fields updated. I've closed Custom Property Editor after my import and reopened it. I've verified the lack of change via the Database Manager. I've watched the tutorial video and all seems to work the same for me except the end results.
Are there any known issues or gotchas with this? Can UAC be a factor?
Ironically when I move to my new 10.4 installation the lessons learned here will probably be useless as the custom property changing will have been moved to the web interface.
That is strange indeed. Disabling UAC is always recommended. Have you tried launching the custom property editor with right click and choosing run as administrator? Are you logging in with a domain account and if so, could you try again with a local one?
