What's fixed
- "Check for Updates…" sometimes did nothing. A manual click was being silently dropped if the periodic background check was in flight (which happens right after launch and every 6 hours). Now a click during an in-flight silent check upgrades the result to surface a visible alert. Multiple clicks coalesce into one alert.
