Just tested, v2.6.3 on Win 10 pro 1703, and I can edit standard, and custom, fields metadata without problem, from the Windows Explorer detail pane, preview pane (using the
preview handler tools metadata edit pane) and file properties dialog details and
InfoEdit tabs, so all still working as designed.
What's happening in your case? Does it show any error message when saving the changes or the fields are just read only?
Run the
manager and recycle the Property Handler extension registration. I.e. uncheck it and apply the changes and then check it and apply the changes again.
Now, using the Windows task manager, select the Windows Explorer process and click the restart button.
