91337 - double-click is detected even if two clicks were on different objects

Status: RESOLVED WORKSFORME

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

Description

[Jesse Ruderman]

Split from bug 53485, Mozilla too lenient on double-click detection (timing).

Mozilla doesn't check if you clicked on the same thing twice when detecting
double clicks.  If you click on one thing, move the mouse a pixel, and quickly
click on another thing, the second thing will get a double-click.

Steps to reproduce (must be done quickly):1. Click on the edge of a mail message
entry in the thread pane.
2. Move the mouse down one pixel so it's now over a different message.
3. Click again.

Result: the second message is selected and shows up in the message pane.  A few
seconds later, a standalone message window appears.

Expected: the second message is selected and shows up in the message pane, but
nothing else should happen.

I've hit this several times since I started using Mozilla Mail as dogfood, but I
just now figured out that it was happening because of this double-click
detection problem.

I just started noticing this in 1.1alpha.  Has it always been around?  or  did
it just crop up now?  I'm noticing it specifically for the case of clicking on
one message and then clicking on a message directly below it.  Of course,
clicking on white space directly below works as well.

Over to default owner; this is a major pain in mailnews (see bug 201879)

WFM?

[Mike Christie]

The behaviour outlined in the original comment now works for me too.  However, the behaviour described in comment #9 is still a bug.  I can't Alt-Tab fast enough to reproduce as described, but if two windows are placed next to each other I get a double click effect on the second window if I rapidly click first in one window and then in the other.

I still see the original bug (as described in comment 0) in Thunderbird 1.5 (20051201).  But now it's the first message that gets opened in a new window, not the second message.

I also see this bug (as described in comment 0) in the bookmark manager of Firefox.  Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20060107 Firefox/1.6a1

is there a FF bug# and TB bug#?   bug 53694 is the SM equivalent, which I just closed WFM (and reopened cause I just got to fail under harder testing)

Not a 1.9 blocker.

[Rainer Bielefeld]

NOT reproducible with Test document and German SeaMonkey 2.32.1 Build 20150204202218 on German WIN7 64bit
And: Before we talk about a Mozilla Bug it should be proved that on the same Computer other programs do not show the complained behavior.
I am tending to see this one as UNCONFIRMED.

Not reproducible any more. Tested: Thunderbird 24.5.0 Linux.

This issue has appeared for me in Thunderbird version 102.7.1 on Windows 10. As one of the comments above says, I also see this issue in the Firefox Bookmark Manager on version 109.0.

I can reproduce the issue consistently by following these steps:

1. Open an IMAP email account in Thunderbird so that at least the subject line of more than one email is visible
2. Click the first subject line, then with only a small time gap, click the second

Expected Result: The first email loads in the viewing window on the first click, then the second email loads in the viewing window on the second click
Actual Result: The first email loads in the viewing window on the first click, then the second email opens in a new tab on the second click

Let me know if I can provide more information to help track down this bug.

I apologize, I determined this issue to be due to an unexpected issue with my operating system configuration. Please disregard, and thank you for your work!
