From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:0.9.4) Gecko/20010913 BuildID: 2001091303 When I log out of Windows NT4sp6a with turbo loaded, Mozilla doesn't seem to receive the shutdown message; NT gives the dialogue box saying the app won't shut down gracefully and asking me to wait, kill it or cancel. Just to make things annoying, this doesn't happen every time. Reproducible: Sometimes Steps to Reproduce: 1. Start->Shutdown 2. 'Close all programs and log on as a different user' 3. Hit 'Yes'. Actual Results: Mozilla.exe has failed to shut down. Wait, kill it or cancel? Expected Results: Exited gracefully when the system told it to. Possibly related to bug 100319 (Turbo: Hangs or does not allow Windows 98 to shut down) or bug 100874 (turbo should respond to ctrl+alt+del kill)? They're the closest I found in bugzilla to this problem.

Reporter: Please try a more recent build to see if that alleviates your issue: http://ftp.mozilla.org/pub/mozilla/nightly/latest/mozilla-win32-talkback.zip -> XP Apps: Cmd-line Features

This is likely a legitimate problem. We have no code to handle WM_QUERYENDSESSION and/or WM_ENDSESSION. The behavior when in turbo mode is just another symptom of the same problem. See also bug 14807.

Marking NEW as per Bill's comment.

Just tested this in today's build (2001092503), as requested. * In turbo mode, bug 101500 still applies - Windows is unable to get Mozilla to shut down, and comes up with 'Wait/End Task/Cancel' dialogue box. * When not in turbo mode, Windows succeeds in shutting down Mozilla itself, but the shutdown is not quite graceful - an open Composer window with unsaved text was killed without the 'Save/Don't Save/Cancel' warning. I think this isn't quite a duplicate of bug 14807.

Adding block: bug 75599.

dup of 100319?

Indeed; note that the other related bug, bug 14807, is really the same problem. When we properly handle system shutdown, then we'll save composer window *and* prevent the "not responding" alert. *** This bug has been marked as a duplicate of 100319 ***
