Combo selection bug? [message #461457]

Hi,

I have a very simple example using Combo:
Combo combo = new Combo(parent, SWT.NONE);
combo.add("abc");
combo.add("ab");
combo.add("def");
After i select the item "ab" from the drop down list, the string "ab" is
displayed in the text widget of the combo. But when I click the drop down
arrow again, the selected item in the drop down list changed to "abc". It
seems that the string "abc" has a prefix "ab" which match the text in the
text widget, so it is selected. I don't know why the combo can't keep the
previous selection. By contrast, if i select "def" and click the drop down
arrow again, the "def" item is still selected. I want to know whether it
is a bug in Combo? or something wrong with my program?

I will appreciate your answer!

Sounds like a Windows bug (assuming you are running Windows).
