I created a Combobox which is suppose to scroll through a grid given the keystrokes of the user. It works perfectly at home.

Example: Type S M I might move you to the first SMITH record.

While out doing some installs, I found that some computers would do S M I and others would only do S; regardless of the way you type fast or slow. Is there some Windows setting that might affect the ability to type multiple characters into an Incremental Search ComboBox?
