If you click on the dropdown arrow of a ComboBox and then type a letter, that first letter is ignored in the search.
Here is a repro:
•Go to the sample ComboBox at http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/ComboBox/ComboBox.aspx
•Click on the dropdown arrow (so that the list appears)
•Type the letter "J". Instead of going to the first list item starting with "J", the KeyPress is swallowed.
•Type the letter "J" again. This time you are brought to the first item starting with "J"
I looked through the JS and sure enough it is just setting focus to the textbox on the first key press.
