Do you use the Qt5 or the Q6 version of the Windows installer ? Go to Help/Components Info for details...

I'm assuming you're using the Qt6 version, and you don't see a popup window when you drop onto PersonA, right?
This is currently a known bug in the Qt6 version. However, it doesn't occur on every Windows installation. I have three Windows computers here that don't have this issue.

Comment 4 HubMiner 2025-08-12 12:25:59 UTC

The issue is present in the latest version: 

digiKam: 8.7.0
KDE Frameworks: 6.12.0
Qt: Using 6.8.3 and built against 6.8.3
Windows 11 Version 24H2
Build ABI: x86_64-little_endian-llp64
Kernel: winnt 10.0.26100

Comment 5 caulier.gilles 2025-08-12 12:28:26 UTC

Be patient. I think that the issue come from the Qt 6.8.3 version used to build the Windows installer.
In VCPKG framework used to build under Windows, Qt is not updated to 6.9.0. I plan to rebuild all today or tomorrow.

Best regards
