@technicat the original Mac UI devs noticed and solved so many problems in *1986* that more recent Web 2.0+ frontend devs just ignore -- like this one, *drag delay* -- solving the problem that when the user moves their cursor towards an item on a popup menu, the mouse may drift outside the lines momentarily *en route*, so you should make sure not to close the menu prematurely; these days lots of popup menus instantly pop closed if you stray outside their bounds #UI #UX
