User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de-DE; rv:1.7.10) Gecko/20050717 Firefox/1.0.6

A newly added language cannot be moved up/down with the buttons if the end of
the language list cannot be seen at the time of adding the new language. The new
language also cannot be selected. This sounds strange but try it!

Reproducible: Always

Steps to Reproduce:
1. Open Preferences => Language
2. Add some languages so that the list so long, that a scrollbar is shown
3. Scroll up the list and select an item, so that the end of the list is not shown
4. Add a new language
Actual Results:  
The language is added to the end of the list but the new language cannot be
selected in the list. 

Expected Results:  
The language should be added and the new language should be selectable.

Confirmed bug in Deer Park Alpha 2, Mozilla/5.0 (Windows; U; Windows NT 5.1;

So can we close it as duplicate? Which bug number is it for Deer Park Alpha 2?

Comment 3

[Adam Guthrie]

This looks very similar to the issue in bug 279497.

This bug also exists in 1.5 beta 1.  A workaround is to click Ok and get back
into the Languages dialog box; the bottom language is now selectable.
