Combo box enhancement (applies to INFLD and XTREE selection-only combos): Replace the standard Windows single-character keyboard matching algorithm with a multi-character version, thereby allowing direct keyboard selection of items from within combos which share one or more starting characters. Previously, the matching logic reset for each new character, making it impossible to select by anything other than the first character of the item. Now the matching logic resets after a delay of 1 second, or after a failed match or a special key such as Arrows.
