Sometimes apps are moving targets as if they were games. I propose a grace period of maybe 250 ms after a visible change. Let's say I click a button but the window poof! disappeared just exactly then and revealed a different button beneath the closed window. Aargh! Now I caused something else! My contrarian opinion is that we should try out this: if a button disappeared visually it is still there for 250 ms more. So we aren't caught by the GUI change. After 250 ms we can react and cancel the intention to click. I am sure we need to experiment with the time needed and make it configurable.
