A click that could not be delivered no longer passes for a click that worked

You press Install and immediately move to another page. The press is on its way to the server; your page closes behind it; the press arrives a fraction of a second later and finds nothing left to hand it to.

Until now that press was quietly dropped. The page you had left showed nothing, the page you had moved to showed nothing, and the only trace was one server line that looked exactly like the routine housekeeping the server writes whenever a page closes. Anything that later went looking for the result — you, a colleague, an automated check — saw an absence indistinguishable from you never clicked at all. In one measured case that cost a five-minute wait for a package that was never going to appear.

What changed: an action that cannot be delivered is now refused, not discarded.

• If anything of yours is still connected, you get the standard error message: your last action did not run, nothing was changed, please try again — in English or German, in your language, naming what you clicked.
• Whoever is running the portal gets one clearly-worded error naming the action, the place and the page it came from, instead of a housekeeping note.

Ordinary page housekeeping is untouched and stays as quiet as it was — the change applies only to things a person actually did: a click, a dialog you closed, a field you left.

What it does not do: it does not make the press happen after the fact. Once the page is gone the work it would have started has nowhere to run, and pretending otherwise would be worse than saying so. What you get instead is the truth, quickly, on whatever is still in front of you.
