19181 - alt-tab to task-switch activates the "file" menu

Status: VERIFIED DUPLICATE of bug 17749

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

Description

[vocatan]

When using the ALT-TAB combination to switch the current application on
WindowsNT, intermittently the "File" menu will be activated. (This is the same
behaviour as if I just pressed "ALT" by itself from within the application).


This is inconsistent with other Windows applications whereby the ALT-TAB event
is trapped and NOT passed to the underlying application (and hence the cursor
focus remains where the user was typing and doesn't move to the menu bar instead).

This is another DUPLICATE of bug 17749, which is itself almost certainly
a duplicate of 17683. In all of these cases, the problem seems to
be that the effect of the ALT key is carrying on beyond when it should be.
Try typing in the Location Bar after ALT-TABbing to Mozilla: the menus will
appear in turn as you type any character that is the beginning of a menu name!
Or, for the minimal case, type a character anywhere you can enter test,
press and release the ALT key, type "f", and watch the File menu drop down.

Changing Component from "Viewer App" to "Event Handling" - Marking DUP.

The reporter is right about one thing for sure - ALT-TAB should never be
responded to by a Windows App, it should always be sent along to Windows
itself by the app that had focus before the ALT-TAB. It doesn't seem that
Mozilla is improperly picking up ALT-TAB events, though, just improperly
picking up ALT-modifiers that should no longer be present.

Marking Verified as a dup.
