16948 - [CRASHER] pressing [ESC] in editor crashes all open windows

Status: VERIFIED WORKSFORME

(Core :: DOM: UI Events & Focus Handling, defect, P3)

Description

[Sean Richardson]

Summary:
Pressing the [ESC] key at any time while the Editor window has focus
(except if drop-down menu is active, see bug 16944 for that) will
crash all mozilla windows currently running.

Steps to reproduce.
1. Start mozilla.
2. Start the Editor with File>New>Edit Blank Page.
3. Do anything; if you want to lose some work, do it here and now,
   and don't save.
4. Press the [ESC] key.

Actual results:
The Editor will crash, taking everything with it.
This happens even if a dialog is open that should get the [ESC] and cancel.

Expected results:
Normal behaviour for the [ESC] key: dismiss something if there is something
to dismiss, otherwise nothing.

Tested with:
Windows NT 4.0sp3, mozilla.exe, 1999-10-20-08-M11 build

Additional Comments:
Not sure if this is a problem with Event Handling or Editor code.

This doesn't reproduce for me at all.  Can someone else try it and reopen with
more detail on how to reproduce if they see it?  I tried hitting esc all over
the new editor window and had no problems.

Works for me too with the 1999-11-07-08-M11 build on Win NT.
As far as more details go, there are none... with the build this bug was
reported against, pressing [ESC] at *any* time when the Editor window had focus
caused a crash, unless a menu was active - 100% reproducible, no special
  instructions needed. This may have beenatransitory problem in the first
place, although I saw it on more than one build.
