378321 - Buttons in "Advance to next folder" query have the wrong SPC default

Status: RESOLVED DUPLICATE of bug 378108

(Thunderbird :: Mail Window Front End, defect)

Description

[Andreas Fuchs]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-US) AppleWebKit/420+ (KHTML, like Gecko, Safari/420) OmniWeb/v607.17
Build Identifier: version 2.0.0.0 (20070326)

When asking whether to advance to the first unread message in the next mailbox, Thunderbird 1.5 used to open an Ok/Cancel type message box, with OK as the default for activation with the Return key (and on the Mac, for the space bar as well). 

In 2.0, it opens a Yes/No type query, and the default for hitting Space on the Mac is now "No", which to me is a big source of "WTF" moments, as up until 2.0, I used to hit space twice to advance to the next mailbox/newsgroup. AFAICT, this behavior would be consistent with the other platforms (Windows and Linux), as well.

Reproducible: Always

Steps to Reproduce:
In Mac OS X and Thunderbird 2,

1. Go to a folder with no unread messages
2. Have another folder with unread messages
3. Hit N
4. Observe the defaults on the buttons in the dialog box that pops up.
Actual Results:  
Yes will be activated when hitting Return only (it's shiny blue, but has no additional blue border)
No will be activated when hitting Space (has the blue border)

Expected Results:  
Yes should be activated when hitting Return or Space.
