So apparently there’s a weird bug where, on a MacBook Neo (& possibly for other MacBooks w/ rounded corner displays) when you open an installed PWA (from either Safari or Chrome) and click near the very top of the screen, the cursor may briefly relocate to the bottom of the screen.
In LisaGUI, this causes issues selecting dropdown menus from the main menu bar. Among other things, it prevents sticky menus from working. So now I have to add an option to manually capture the mouse, or do some other weird thing to mitigate this issue, which was never a problem before…
