No install. No account. Public and anonymous. The link asks your agent for one report, nothing else. What it sends

Quiet. No reports in the last two weeks, down from 2 a week at the late-September peak. A workaround is known.

Desktop app crashes seconds after startup on Windows. Splash screen or window appears, then the app closes without an error dialog, with a breakpoint in chrome.dll.
