Start11 scrolling issue
Items in Shortcuts list (right-hand side) don't scroll with touchpad
OS: Win11 24H2 Build 26100.2605
Start11 v2.11
Menu Style: Windows Pro style
I generally have two-finger on the touchpad scrolling enabled. I am able to two-finger scroll in the main portion of the Start Menu (e.g., the All apps list).
However, if an item is included in the Shortcuts on the right-hand side that expands into a menu which is large enough to display a scroll bar (e.g., Control Panel), that menu will not two-finger scroll.
