272825 - mouse wheel sometimes not working in message window

Status: RESOLVED EXPIRED

(Thunderbird :: Mail Window Front End, defect)

Description

[icking]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en) AppleWebKit/125.5.5 (KHTML, like Gecko) Safari/125.11
Build Identifier: version 1.0RC1 (20041201)

Scrolling up/down using the mouse wheel (scroll wheel at the middle mouse button) does not work for 
a newly displayed message. It only works after clicking in the window or moving the mouse cursor a 
little bit over the window.

Reproducible: Always
Steps to Reproduce:
Subscribe to a newsgroup or an rss newsfeed with many unread, long messages.

Display the first message, let the mouse cursor stay over the message text.

Do not move or click the mouse, just browse from message to message by pressing
the space key.

If a new message is longer than the height of the window try to scroll down using the
mouse wheel. Nothing happens. Press the space key to get the next message, try to
scroll down, nothing happens, etc.

But if you click once on the new message, then the scrolling works,
also after you just move the mouse cursor a litte bit over the window then
the scroll wheel is recognized.

BTW: The scrolling speed of the mouse wheel is too fast, if it works,
much faster than in Firefox.
Actual Results:  
Scrolling up/down does not happen.

Expected Results:  
The content of the window should scroll up/down when using the mouse wheel, but immediately,
not only after clicking in the window or moving the mouse cursor around.

I also have this problem, but I found one detail of information left out from
the original report.  Here is what I do to reproduce this bug, and also what I
have observed:

1. Open a message (without moving the mouse at all)
2. Use the mouse wheel to try and scroll the message
3. Observe the thunderbird mail window and see that either the folder list or
the message list will scroll instead of the actual message.
4. Move the mouse even just a few pixels.
5. Scroll behavior now works in the actual message instead of the mail list window.

It seems to be a focus problem.  The focus does not leave the main window until
you click in the message or move your mouse over the message window. This is not
limited to RSS feeds.

I've observed this in Thunderbird 1.0 (20041206) and also in Thunderbird 1.0.2
(20050317).  I'm running MacOSX 10.3.9.

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.
