Hi,
I created a quick pull request that fixes the window dragging issue on the latest update of rhino 8 on windows.
Here you can test it:
https://github.com/Eromoleon/humanui/releases/download/v0.8.11/human-ui-0.8.11-rh8_0-any.yak
As far as I see everything works still, but only tested this on Rhino 8.36.26296.17001 Windows.
Cheers
Tamas
