I never did create a GitHub account, sorry, but these discussions about building the Windows AIO for v6.0.7 suggested that trying to help would be beyond my skills.
Now that the AIO for v6.0.7 is available though, I have installed it. As usual after an update the first time I opened Gramps, a console window opened behind the main window. In the past that console has been empty. This time though it said:
db changed: <sqlite.SQLite object at 0x0000022932b1a510>
I have no idea what that means, other than the obvious that something in the db was changed. Despite this, Gramps appears to be working as expected.
