This problem is even older, but was not as prevalent as now. Early 1990 I experimented with Mosaic, and I experienced it the first time: I wanted to click on something but in the few hundreds of milliseconds between my decision to click and really clicking an alert popped up and I accidentally dismissed the alert and couldn't read the message. This does not only happen on the web. All GUI software suffer from this problem. I know that Office products also have caused me to misclick because something just appeared or disappeared. I have been thinking about a tweak to the GUI: Let things appear or disappear but still accept click events for about 200 milliseconds longer. As if the change did not happen yet. Perhaps combine this tweak with a soft but quick blending-in of the change, and only enable the new GUI after the blending-in finished. This is different from the problem that GUI buttons move but at least related. Perhaps with this tweak moving GUI buttons won't annoy as much, because we can react. This is not ideal, but not as bad.
