Rhino 8 - Bug - Adjust Surface Blend popup UI - Slider not sliding

Current Release (8.9.24163.15301, 2024-06-11)

When I use the Blend Edge command I can’t adjust the sliders in the ‘Adjust Surface Blend’ popup - the focus jumps way as I click and try to drag. I can only click somewhere else on the slider bar and then the slider will move to where I click. I mainly enter exact numbers but like to use the initially to get a feel what’s working…
