Hello,

I've tried to upgrade a project from 2011.2 to 2012.1 and think I may have found a regression bug.
I've managed to reproduce the problem in a minimal project file, which you can find attached.
The expected behavior is the typing a key press is immediately reflected in the combo, and the drop-down should expand (according to the properties I've set)

            this.ultraCombo1.AutoSuggestFilterMode = AutoSuggestFilterMode.Contains;
            this.ultraCombo1.AutoCompleteMode = Infragistics.Win.AutoCompleteMode.SuggestAppend;

In other words, if I type the letter 'w' in the edit-part of the combobox, the current select text should be overwritten and replace by w.
However, it is not what happens: for example, if I type 'w', the drop-down list expands, but the text is not reflected in the edit-part of the combo.

I need to type 'w' a second time for the letter to appear.
I've tested the exact same code with 2011.2 and I don't get this problem at all and it works as expected.
I tried with 2012.1 SR 2024 (12.1.20121.2024) but it still has the problem.

I don't think I'm doing anything wrong in this code, but if I do, please could you let me know, and if not, consider the bug to be fixed in the next SR?
Thanks a lot in advance,
