http://gambaswiki.org/bugtracker/edit?object=BUG.2208&from=L21haW4-

Claus DIETRICH reported a new bug.

Summary
-------

Wrong Sorting of ListBox

Type             : Bug
Priority         : Medium
Gambas version   : 3.16
Product          : Unknown


Description
-----------

When the ListBox sorted-property is set to True its sorting only works correctly with capital letters. As soon as the first character of the list-item is a small letter the sorting fails and the item is put behind list items with capital letters.

I attached a very small demo snippet for reproduction which also shows a listview-control for comparison, where the sorting works correctly.
