Mouse not captured by Windows 7 guest with VB 6.1.0, 6.0.14 or 5.2.10 on macOS Sierra host

[DamienDeville]

After migrating from guest Windows 7 to 10 with VB 6.0.14 on host macOS Sierra (which was working fine with guest Windows 7), the full-screen option host F would not work even after installing the guest addition on Windows 10.

So I reverted back to Windows 7 and the full-screen was no longer working. I tried to uninstall and reinstall the guest addition and it destroyed the mouse integration which is now disabled after starting the VM even though it is enabled on the setting menu.

Now I can't figure out how to install the guest additions without a working mouse as the it involves clicking on Windows buttons inaccessible from the arrow keys of the mac keyboards which just do not move the cursor from one button to the next. The mouse of the host does not merge with the mouse of the guest. So now I am stuck with a completely unusable VM. I tried to upgrade to VB 6.1.0 and downgrade to 5.2.10 from a backup but still no mouse integration with either of those.

I tried to change the pointing device from USB tablet to PS/2 Mouse, the graphic controller to VBoxVGA, VBoxSVGA and even VMSVGA, the USB controller to 3, 2 and 1, disable my filters, enable and disable 3D and 2D acceleration, but none of these attempts make neither the mouse integration nor the full screen option work.

Any suggestion?
