307810 - Character encodings dropdown boxes only work when Thunderbird is first started

Status: RESOLVED DUPLICATE of bug 315057

(Thunderbird :: Preferences, defect)

Description

[Ed Buffey]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b4) Gecko/20050909 Firefox/1.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b4) Gecko/20050908 Thunderbird/1.4 ID:2005090804

In the Tools/Options/Display/Fonts dialog, in the character encodings section,
there are two dropdown boxes for selecting the character encoding for mail. When
Thunderbird is initially started, both dropdown boxes include all available
choices for character encoding. After you dismiss this dialog and re-open it,
neither dropdown box works. Each dropdown box has only one option--whatever
option was selected during the previous time the dialog was open.

Reproducible: Always

Steps to Reproduce:
1. Start Thunderbird.
2. Using the Tools menu, select Options.
3. Click on the Display category.
4. Click on the Fonts tab.
5. In the Character Encodings section, try pulling down each of the dropdown boxes.
6. Note that they both work no matter how many times you do it.
7. Dismiss the dialog by using the "X" or the Ok or the Cancel buttons.
8. Repeat steps 2 through 5.
Actual Results:  
The dropdown boxes refuse to drop down. They only show the options that were
already selected.

Expected Results:  
The dropdown boxes should have shown all available options as they did in the
original step 5.

I can reproduce this on 1.5 Beta 1 Win32 build (20050908), with the same steps
to reproduce.

Also in 1.5b1-0904, Win2K.  Not present in 1.6a1-0904.

Bug 285076 just fixed a similar symptom (and a host of related ones) on the 
trunk.

Linux too.

Interesting how this was marked as a blocker for 1.5, but didn't get fixed before 1.5.

I still see this with version 1.5 (20051201) on Windows XP.

Duping this to a later bug, because that's where Scott explicitly said this problem doesn't qualify as a blocker.  Sorry for not seeing the dupe earlier.
