This issue seems to be related to ATE 6.0 only:
In a combo box, hitting the first character of the string will bring up the first matching entry. If I continue to type the same letter in 5.x it would give me the next match (which i believe is correct/standard). In 6.0 it does not show me any more matches.
(works with 5.1 ATE / 6.x server so it smells like an ATE issue vs server)
Thanks.
